Curved waveguide HUD
10/05/2021: P.-A. Blanche, and C. T. Draper, “Curved waveguide combiner for HUD/AR“, Proceedings Volume 11828, ODS 2021: Industrial Optical Devices and Systems; 1182806 (2021). Link
In this article and presentation, we are introducing for the first time to our knowledge, the use of a curved waveguide (instead of flat), as a combiner for HUD/AR applications. Curved waveguides can find applications in automotive HUD (windshield), motorcycle (helmet visor), and AR glasses (curved lenses and prescription lenses).
SPIE Optics & Photonics meeting
08/01/2021: I will be presenting a paper and chairing a session about Measurement and Sensing during the SPIE Optics & Photonics meeting in San Diego. Link
Paper 11828-14: “Curved waveguide combiner for HUD/AR” 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.
Photonics Spectra Conference
01/20/2021: I will be presenting “A Virtual Tour of Holographic Combiner Elements Targeting HUD/AR Applications” during the 2021 Photonics Spectra Conference. Link
The organizers let me know that over a 1700 people registered for my specific talk. The conference seems to be a huge success.
