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 … See more Currently, several companies and university departments are researching on the field of CGH devices: • VividQ provides software for real-time CGH devices, … 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), … See more
