Title: “Fringe Projection Profilometry: a Critical Tool for Our Freeform Panel-forming Research

Abstract: There are a myriad of metrology methods to measure smooth, specular optics, ranging from deflectometry to interferometry to wavefront sensors to Ronchi Tests. However, there is lacking methods to measure surfaces that are not so specular, yet still need high accuracy. This problem became apparent to us in the Steward Observatory Solar Lab where we are working to produce freeform radio antenna reflectors at low cost. There was simply nothing out there useful to us beyond CMMs or laser trackers, both of which are very costly, take up space and have slow data collection. This led us to develop a touchless method based on fringe projection profilometry. The method commonly uses one camera, but we integrate two cameras to the system to eliminate errors from a variety of sources. We have been using the system for the last year and half as a research tool for the entire lifecycle of producing antenna panels and assembling the final dish, along with other various applications.

Bio: Joel Berkson is a 5th year PhD candidate, graduating in Winter 2023. His research has spanned everything from optical design, optical fabrication and alignment, and optical metrology.

Title:Designing Freeform Optics with the Wave Aberration Polynomial Surface Type

Abstract: As the viability of freeform imaging optics grows, it is important that design methods evolve concurrently. Toward this end, we introduce the wave aberration polynomial, a novel freeform surface type derived directly from the wave theory of aberrations, and discuss its benefits over other popular freeform surface representations. We further propose a method to design freeform imaging systems, which will be outlined through examples of all-reflective, unobscured microscope objectives (up to NA=0.70), pupil relays, and tube lenses. We will conclude with a brief discussion of the optomechanical design and fabrication strategy of a 40x/0.53 four-mirror microscope objective.

Title:Controllable Generation of Higher-Order Transverse Modes in VECSELs

Abstract: Higher-order transverse modes have been a forefront research topic stemming from some of the initial work on the laser; however, in the past decade Laguerre-Gaussian modes have experienced renewed interest in part due to the orbital angular moment (OAM) these modes carry. The structure and phase of these modes result in many applications including optical communication, nonlinear optics, atom and particle trapping and manipulation, and imaging sciences. The vertical external cavity surface emitting laser (VECSEL) provides an excellent platform as a source for these uniquely structed modes. In this presentation the development of higher-order mode tunable VECSELs will be summarized.

Bio: Nathan is a research associate within Dr. Mahmoud Fallahi’s research group which specializes on vertical external cavity surface emitting lasers (VECSELs).

Title: “Imaging-based Quantum Optomechanics

Abstract: Quantum optomechanics studies the interaction between mechanical systems and light via the radiation pressure interaction, and has led to advances in quantum sensing, optical manipulation of mechanical systems, and quantum technologies. However, previous studies have typically focused on optomechanical coupling between light and translational mechanical degrees of freedom, such as the drum mode of a membrane, which modifies the amplitude and phase of the light field. Here, we discuss recent advances in “imaging-based” quantum optomechanics – where information about the mechanical resonator’s motion is imprinted onto the spatial mode of the optical field. Therefore, optimal measurements of the motion are comparable to studies within quantum imaging. We discuss the sensitivity limits of “imaging-based” measurements of mechanical oscillators, including the effects of shot noise and radiation pressure noise. We also highlight recent experimental advances, including measuring an ultra-low mechanical dissipation torsion mode of a silicon nitride nanoribbon using a variety of measurement techniques, including an optical lever and a spatial-mode demultiplexer. Finally, we note the potential for squeezed light-enhanced imaging measurements of these devices, as well as producing squeezed light in higher-order spatial modes via this optomechanical interaction.

Bio: Christian is a 6th-year PhD student working in Dal Wilson’s lab. In his time at the Wyant College of Optical Sciences, he has worked on room-temperature quantum optomechanics experiments, including experiments to observe quantum behavior in macroscopic objects and squeezed light-enhanced measurements of mechanical motion.

Title:A Simple Method for Comparing Sensor Range Performance with Small Pitch LWIR and MWIR Detectors

Abstract: There have been several papers in the past 10 years that describe the performance benefit of super-resolution, the optimal size of LWIR and MWIR detectors, and a simple model for predicting target acquisition range performance. A diffraction-limited infrared system has a range performance in good atmospheric conditions proportional to D/lambda, where D is the aperture diameter and lambda is the wavelength. For a non-diffraction-limited infrared system, Flambda/d (where F is F-number,lambda is wavelength, and d is the detector pitch) is a measure of how close to D/lambda (diffraction-limited performance) that you can achieve with the sensor. These two quantities provide a simple way to compare sensor range performance. We summarize how these metrics impact super-resolution, LWIR detector pitch, and MWIR detector pitch. For those who want to understand what this means in optical blur spot compared to detector size, we provide an equivalent spatial metric.

Title:Fiber Optic Plates as Light Guides for Scintillation Cameras

Abstract: The detection of high-energy photons using a scintillator requires thickness to create stopping power. The thickness of the scintillation crystal introduces parallax error in pinhole collimated systems unless the depth of interaction is accurately determined. We have considered whether introducing fiber optics to control the spread of light between a scintillator and an array of light sensors can improve 3D-position estimation. We thus developed a Monte Carlo light-transport simulation for an SiPM-based modular gamma camera that incorporates a fiber optic-plate in the light guide. This created a computational challenge due to the very large number of reflective and refractive surfaces that scintillation photons can encounter. We wrote a custom code in the Swift programming language that is capable of modeling the complicated trajectories. We performed the most computationally taxing components on GPU cores using the Metal framework. This code included refraction according to Snell’s law as well as reflection according to Fresnel’s laws at all index-of-refraction boundaries. We used the simulation code to create mean-detector-response functions (MDRFs). The predicted 3D spatial resolutions of cameras with and without fiber-optics were compared by using Fisher Information Matrices to calculate the Cramér-Rao Lower Bounds on position-estimate variances.

Title:LWIR Spectral Polarimetry for Ice/Water Discrimination

Abstract: The University of Arizona Polarization Lab developed an Infrared Channeled Spectro-Polarimeter (IRCSP) to measure linear Stokes parameters with 1K polarimetric accuracy and 1um average spectral resolution between 8-11um. Emissivity and refractive index in this spectral band are known to depend upon water’s kinetic temperature and thermodynamic phase. In this work, the theoretical thermodynamic phase discrimination capabilities of spectral Long-Wave-Infrared (LWIR) polarimetry are demonstrated with IRCSP. In a room temperature laboratory environment, IRCSP measurements of melting ice are shown to depend on the view angle, wavelength, and thermodynamic phase. As the solid ice melted for 10 minutes, IRCSP measured a constant brightness temperature of 276K between the time-lapsed samples. The difference in the degree of linear polarization (DoLP) between solid and melted ice was 7% on average and peaked at 13% in the 9.5-10.5um waveband. This observation is an example of enhanced sensitivity to thermodynamic phase change using LWIR polarimetry.

Bio: Jaclyn is a 3rd year PhD student in the Polarization Lab. Her research involves using thermal spectro-polarimetry for remote sensing applications. The instrument used in her work was just recently deployed on a high-altitude balloon out of NASA Columbia Scientific Balloon Facility for cloud observations.

Title:Simultaneous Estimation of Surface Normal and Absolute Depth from Mueller Polarimetry
Advisor: Meredith Kupinski

Abstract: Conventional shape-from-polarization (SfP) techniques make use of partial polarimetric information acquired from Stokes imaging. Furthermore, conventional techniques require choosing between a purely specular or purely diffuse polarized light scattering model, even though most real-world objects exhibit a combination of these behaviors. Mueller imaging provides complete polarimetric information which enables estimation of not only the shape of an object, but also the absolute depth of the object at seen by each pixel. Analyzing Mueller measurements informs polarized scattering models that realistically mix specular and diffuse behaviors, resulting in improved shape estimates.

Bio: Quinn Jarecki is a 5th year PhD student in the Polarization Lab. His research interests include Mueller imaging polarimetry and polarized light scattering models. He is expected to graduate in Spring 2024.

Title:Super Resolution in Heterogeneous Array Cameras under Coherent and Partially Coherent Illumination: A Generative Artificial Intelligence Approach
Advisor: David J. Brady

Abstract: Single image super-resolution (SISR) research has witnessed advancements with the development of deep learning. However, most existing studies are still fundamentally limited by the resulting physics of their single aperture imaging modalities, bottlenecking the limit of information obtained as input for deep learning based super-resolved reconstructions. Alternatively, by using active coherent or partially coherent illumination, measured object fields exhibit significant image diversity in array camera systems, enabling snapshot Fourier ptychographic reconstruction strategies whose measurement performance can exceed that of a single-aperture system; a typical single-aperture system only being physically capable of measuring a limited region of the field’s Fourier domain. Thus, in this work we investigate a unique direction towards super-resolution with generative AI. To this end, we leverage the sampled image diversity measured by each array camera’s multi-view sampling of the Fourier domain, while utilizing our prior work with neural representations, radiance fields, Neural Radiance Fields (NeRFs), and Transformer networks for fusion of the heterogeneous sensor data. By co-designing the coherent and partially coherent illumination scheme, array camera parameters, generative AI architectures and strategies a flexible and intelligent imaging system can be optimized for super-resolving remote targets.

Title:Design of a 1.0 mm Multiphoton Microendoscope System for Minimally Invasive Detection of Cancer
Advisor: Jennifer Barton

Abstract: Early stage cancer manifests as tissue abnormalities that can be imaged with high resolution imaging modalities. Early detection of cancer is key to improving patient health outcomes. Multiphoton microscopy (MPM) is capable of performing high resolution imaging with preferential contrast targeting endogenous fluorophores indicative of metabolic processes and tissue structure, such as collagen in the extracellular matrix. For minimally invasive imaging in vivo, MPM must be implemented endoscopically. We are developing a 1.0mm diameter endoscopic system capable of multiphoton imaging of small tissue lumens deep within the body. A side-viewing imaging geometry is ideal for imaging these structures. Our endoscope performs multi-channel multiphoton imaging of these ductal structures via helical scanning of a side-viewing distal optical system. A dual clad optical fiber is used to carry 1400 nm femtosecond excitation pulses in the core, and collect visible-NIR light (460 – 890 nm) emission within the 1st cladding. Our distal optical system is comprised of custom designed 3D printed lenses, featuring an aspheric powered surface on the exit face of the endoscope fold prism to achieve high NA.

Bio: Zuzana Adams is a final-year Ph.D. candidate in Optical Sciences at the University of Arizona’s Wyant College of Optical Sciences.

Title:Compressive Hyperspectral Imaging with Tunable Light Source
Advisor: Rongguang Liang

Abstract: Hyperspectral imaging is a powerful technique widely used in biomedical imaging, remote sensing and computer vision, etc. However, traditional hyperspectral imaging methods suffer from a trade-off between spatial, spectral and temporal resolution. With the evolution of learning-based algorithms, compressive spectral imaging has attracted increasing attention with its snapshot mechanism, simple hardware requirements, and advanced recovery algorithms. We have implemented a spectrally tunable light source for compressive hyperspectral research explorations. The flexibility, high degree of freedom and rapidity of this light source can grant higher accuracy and more possibilities for compressive spectral imaging.

Bio: Yuanyuan is a PhD student in the Imaging and Applied Optics Laboratory supervised by Professor Rongguang Liang.

Title:Mitigating polarization aberrations in astronomical telescopes with thin-film optimization
Advisor: Ewan Douglas

Abstract: The Astro 2020 decadal survey outlined high-contrast imaging as a key science goal for astronomy in the next decade. To pursue this, a series of world-class observatories must be made in order to observe exoplanets at an unprecedented angular resolution and contrast. These observatories are uniquely sensitive to polarization aberrations, presenting a new challenge to astronomical instrumentation. We present a method of optimizing spatially-varying multilayer thin film stacks to minimize the influence of polarization aberrations on high-contrast imaging systems. With optimized thin-films we are able to reduce the contrast degradation by an order of magnitude. This design study is presented in an entirely open-source environment using the Poke ray-based physical optics package.

Title:The High Contrast Adaptive-optics Testbed for risk reduction on the Giant Magellan Telescope
Advisor: Laird Close

Abstract: GMagAO-X is a visible to NIR extreme adaptive optics (ExAO) system that will be used at first light for the Giant Magellan Telescope (GMT). GMagAO-X is designed to deliver diffraction-limited performance at visible and NIR wavelengths (6 to 10 mas) and extreme contrasts on the order of 10^-7. The primary science case of GMagAO-X will be the characterization of mature, and potentially habitable, exoplanets in reflected light. GMagAO-X employs a woofer-tweeter system and includes segment phasing control. The tweeter is a 21,000 actuator segmented deformable mirror (DM), composed of seven individual 3,000 actuator DMs. This new ExAO framework of seven DMs working in parallel to produce a 21,000 actuator DM significantly surpasses any current or near future actuator count for a monolithic DM architecture. GMT’s unprecedented 25.4 m aperture composed of seven segments brings a new challenge of co-phasing massive mirrors to 1/100th of a wavelength. The primary mirror segments of the GMT are separated by large >30 cm gaps so there will be fluctuations in optical path length (piston) across the pupil due to vibration of the segments, atmospheric conditions, etc. We have developed the High Contrast Adaptive-optics Testbed (HCAT) to test new wavefront sensing and control approaches for GMT and GMagAO-X, such as the holographic dispersed fringe sensor (HDFS), and the new ExAO parallel DM concept for correcting aberrations across a segmented pupil. In this talk we will discuss the current efforts to prototype the novel hardware components and new wavefront sensing & control concepts for GMagAO-X on HCAT.

Title:Target acquisition performance comparison of active continuous-wave and range-gated imaging systems at 1.6 and 2.1 um
Advisor: Ronald Driggers

Abstract: Active imaging systems can provide increased contrast-to-noise ratio (CNR) and targeting performance over passive systems in low-light and long-range applications. We use both a radiometric model and the Night Vision Integrated Performance Model to compare the performance of active continuous-wave (CW) and laser range-gated (LRG) imaging systems with laser illumination at 1.6 and 2.1 μm, corresponding to the shortwave infrared (SWIR) and extended SWIR (eSWIR) bands, respectively. The imager performance is characterized by CNR as a function of range, as well as pixels-on-target. The modeling results demonstrate increased performance in the eSWIR band over the SWIR band in the majority of cases and increased performance for LRG systems over CW systems in all cases. The in-progress design of an active imaging testbed to confirm these modeling results with field imagery is discussed.

Bio: Joshua Follansbee is a third-year PhD student working in Ronald Driggers’ Infrared Systems group, where he focuses on active imaging techniques.
