Neural \'{E}tendue Expander for Ultra-Wide-Angle High-Fidelity Holographic Display

arXiv:2109.08123v4 Announce Type: replace-cross
Abstract: Holographic displays can generate light fields by dynamically modulating the wavefront of a coherent beam of light using a spatial light modulator, promising rich virtual and augmented reality applications. However, the limited spatial resolution of existing dynamic spatial light modulators imposes a tight bound on the diffraction angle. As a result, modern holographic displays possess low \'{e}tendue, which is the product of the display area and the maximum solid angle of diffracted light. The low …
