Unitary rotation and gyration of pixellated images on rectangular screens [PDF]

open access: yesJournal of the Optical Society of America A, 2015
In the two space dimensions of screens in optical sy stems, rotations, gyrations, and fractional Fourier transformations form the Fourier subgroup of the symplectic group of linear canonical transformations: U(2) F $\subset$ Sp(4,R).

Crosstalk Suppressed 3D Light Field Display Based on an Optimized Holographic Function Screen

open access: yesMicromachines, 2022
A holographic function screen (HFS) can recompose the wavefront and re-modulate the light-field distribution from a three-dimensional (3D) light field display (LFD) system. However, the spread function of existing HFSs does not particularly suit integral
