Incoherent computer-generated holography - Optica
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. … See more Holography is a technique originally invented by Hungarian physicist Dennis Gabor (1900–1979) to improve the resolving power on electron microscopes. An object is illuminated with a coherent (usually … See more The third (technical) issue is beam modulation and actual wavefront reconstruction. Masks may be printed, resulting often in a grained pattern structure since most printers can make only dots (although very small ones). Films may be developed by See more Computer generated holograms offer important advantages over the optical holograms since there is no need for a real object. Because of this breakthrough, a three-dimensional … See more Once it is known what the scattered wavefront of the object looks like or how it may be computed, it must be fixed on a spatial light modulator (SLM), abusing this term to include not only LCD displays or similar devices, but also films and masks. Basically, there are … See more Currently, several companies and university departments are researching on the field of CGH devices: • VividQ provides software for real-time CGH devices, allowing for the generation of images with over 200 depth layers using standard computing … See more WebNov 11, 2024 · Unlike conventional two-dimensional (2D) images, three-dimensional (3D) images reproduced by computer-generated hologram (CGH) have a limited viewing angle by diffraction angle . The diffraction angle of CGH is determined by the wavelength to reproduce the hologram and the pixel pitch of the panel that displays the hologram, as … briggs elementary school district bids
