36.3: Flat‐Panel Coherent Backlight for Holographic Displays with Improved Diffraction Efficiency

Abstract

Coherent backlight is an important component in holographic 3D displays. In this paper, a novel coherent backlight featuring a compact design is presented. The feasibility of this structure is experimentally verified by reconstructing 3D images with a spatial light modulator. The diffraction efficiency of the system is ~4.3%.
