Did you know?
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 … WebMar 5, 2007 · A new method for recording digital holograms under incoherent illumination, which results in a complex-valued Fresnel hologram that is reconstructed in the computer when the 3D properties of the object are revealed. 319 PDF Three-dimensional holographic fluorescence microscopy.
