Photolithographic fabrication method of computer-generated holographic interferograms [PDF]
, 1989 We consider the fabrication of high-quality interferogram-type diffractive optical elements with conventional photolithographic techniques and compare the results with those achievable with electron-beam lithography. The fringes associated with the phase

Optics Express, 2020 We propose a method that reduces the computation time and memory requirement in non-hogel-based hologram synthesis from light field data. The non-hogel-based technique synthesizes coherent complex field for a three-dimensional scene from its light field.

Compression of Phase-Only Holograms with JPEG Standard and Deep Learning
Applied Sciences, 2018 It is a critical issue to reduce the enormous amount of data in the processing, storage and transmission of a hologram in digital format. In photograph compression, the JPEG standard is commonly supported by almost every system and device.

Comparison of beam generation techniques using a phase only spatial light modulator [PDF]
, 2016 Whether in art or for QR codes, images have proven to be both powerful and efficient carriers of information. Spatial light modulators allow an unprecedented level of control over the generation of optical fields by using digital holograms.

Accurate Hologram Generation Using Layer-Based Method and Iterative Fourier Transform Algorithm
IEEE Photonics Journal, 2017 Random phase is always added to the object to diffuse the object light in computer-generated holograms. However, this addition causes considerable speckle noise in the reconstructed image. For improving the speckle noise problem, we propose a new method,

Holographic generation of highly twisted electron beams [PDF]
, 2014 Free electrons can possess an intrinsic orbital angular momentum, similar to those in an electron cloud, upon free-space propagation. The wavefront corresponding to the electron's wavefunction forms a helical structure with a number of twists given by ...
