摘要：

The proliferation of 3D content has created a resurgence of interest in the field of biomedical imaging due to the explosion of 3D data from many sources including geographical data, medical scans, CAD design, simulations, low-cost depth scanners, cinema/TV, and 3D printing. Digital holograms are fabricated using holoprinter or holographic printing devices. These are industrial-scale machines that can manufacture full-color, purely digital-reflection holograms in a manner that is repeatable and reliable. The digital hologram comprises a matrix of holographic pixels, also known as holopixels or hogels. The holopixels are created by the interference of red, green, and blue (RGB) lasers in a holographic medium such as a photopolymer or silver halide film. A holoprinter includes RGB lasers, a spatial light modulator (SLM), beam-steering optics, and a computer to show the images on the SLM along with controlling the whole system.
