MODELLING AND RECONSTRUCTION OF GABOR-TYPE HOLOGRAMS
Dyna, 2011 Los procesos de modelación y reconstrucción de hologramas se soportan en el cálculo de la integral de difracción en su formulación de kirchhoff-fresnel o rayleight-sommerfeld. Dicha integral puede ser evaluada numéricamente por medio de diferentes formalismos: teorema de convolución, espectro angular y transformada de fresnel, entre otras.

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.

Deep DIH: Single-Shot Digital In-Line Holography Reconstruction by Deep Learning
IEEE Access, 2020 Digital in-line holography (DIH) is broadly used to reconstruct 3D shapes of microscopic objects from their 2D holograms. One of the technical challenges in the reconstruction stage is eliminating the twin image originating from the phase-conjugate ...
