Abstract: Angle multiplexing is a crucial technique for volume holographic gratings in grating-based lightguide display systems, enabling an extended image field of view (FOV). However, Bragg mismatch diffraction caused by different angle-multiplexed gratings introduces crosstalk, leading… read more here.
