Computer-generated holography - Wikipedia

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 … WebThe remaining chapters explore holographic interferometry, color holography, and computer-generated holograms.
