Reducing crosstalk of a multi-plane holographic display by the time-multiplexing stochastic gradient descent.

Optics Express, 2023
Multi-plane reconstruction is essential for realizing a holographic three-dimensional (3D) display. One fundamental issue in conventional multi-plane Gerchberg-Saxton (GS) algorithm is the inter-plane crosstalk, mainly caused by the neglect of other ...
