Review Article

10/04/2021: P.-A. Blanche, J.-W. Ka, N. Peyghambarian, “Review of Organic Photorefractive Materials and Their Use for Updateable 3D Display“, materials (MDPI), Materials 2021, 14, 5799. Link

In this article we are reviewing:

  • The photorefractive effect.
  • The specific characteristics for a material to be used in 3D display.
  • The different molecules found in photorefractive polymers.
  • How to make samples for holographic display.
  • The setup to record and display 3 color holographic 3D stereograms.

SRC Spotlight

08/02/2021: Congratulation to Craig Draper that was put in the spotlight by SRC (Semiconductor Research Corporation) for his work with the Texas Instruments Phase Light Modulator (PLM) as a light engine for holographic waveguide HUD and augmented reality display. Link

OSA Imaging and Applied Optics Congress

07/19/2021: I will be presenting two papers and chairing the session on Metrology and Profilometry during the OSA Imaging and Applied Optics Congress. Link

Our first paper is DW4B.3: “Texas Instruments Phase Light Modulator for Holography“. The Texas Instruments Phase Light Modulator (TI PLM) is a new type of MEMS that modulates the phase of the incoming light by moving micro-mirrors up and down. We characterized this device for beam steering and for the projection of holographic images.

Our second paper is DF2F.4: “Curved Holographic Waveguide Combiner for HUD and AR Display“. We are presenting a curve waveguide combiner with holographic optical elements that are compensating for image propagation aberration. Both ray tracing model and early experimental demonstrator are discussed.

In this article we are demonstrating the best shape to obtain a fluid cylindrical lens, which focal distance can be adjusted without introducing aberration.

This article was selected by OSA to appear in the “Spotlight on Optics“. Link
