Computer-generated holography (CGH) is the method of digitally generating holographic interference patterns. A holographic image can be generated e.g. by digitally computing a holographic interference pattern and printing it onto a mask or film for subsequent illumination by suitable coherent light source. Alternatively, the holographic image can be brought to life by a holographic 3D display (a display … WebMay 1, 2024 · We propose an incoherent encoding system for image encryption utilizing the coded aperture correlation holography (COACH) technique. Incoherent imaging is the core component of this proposal, in which the point spread hologram (PSH) of the imaging system serves as the main key to encode the input intensity distribution.

"WebSince a general flat hologram has a limited viewable area, we usually cannot see the other side of a reconstructed object. There are some holograms that can solve this problem. A cylindrical hologram is well known to be viewable in 360 deg. Most cylindrical holograms are optical holograms, but there are few reports of computer-generated cylindrical holograms.
