Analysis of new optical addressing strategies for the optimization of retinal projection display

Augmented Reality (AR) is now subject to a great technological acceleration. Different actors of the field develop many different projection technics. However, with each projection technic comes display strategies to improve the comfort and immersion of the user and the quality of the image displayed. Some recent works propose to use new principle of projection based on unconventional optics to create new products aiming to reduce many of the current problems related with the conventional projection principle of AR devices. CEA Leti recently proposed a disruptive optical concept for AR display[1], which is based on the interaction of a grating of monomode linear waveguides with pixelated holograms. This work uses simulations to analyze optical issues associated with this new optical concept. The main topic covered is the study of the SNR depending on the resolution criteria chosen.
