We propose color optical scanning holography (OSH) that records red, green, and blue (RGB) holograms of real objects by single scanning. The proposed color OSH composes a RGB multiplexing unit, color time-dependent Fresnel zone plate generation unit, scanning unit, space-integrating photodetection unit, and demultiplexing unit. In the proposed color OSH, RGB beams follow a common path from the multiplexing unit to a photodetector, generating an electric current containing the object's complex RGB hologram information. In the demultiplexing unit, the complex RGB holograms are extracted and arranged as a complex color hologram. In experiments, we record the complex color hologram of a three-dimensional object composed of RGB transparencies using the color OSH. Numerical reconstruction shows that the recorded hologram contains information about the object's color as well as the diffracted field from the object.
我们提出了彩色光学扫描全息术（OSH），它通过单次扫描记录真实物体的红色、绿色和蓝色（RGB）全息图。所提出的彩色OSH由RGB复用单元、与时间相关的彩色菲涅耳波带片生成单元、扫描单元、空间积分光电探测单元和解复用单元组成。在所提出的彩色OSH中，RGB光束从复用单元到光电探测器遵循共同路径，产生包含物体复RGB全息图信息的电流。在解复用单元中，复RGB全息图被提取并排列成复彩色全息图。在实验中，我们使用彩色OSH记录了由RGB透明片组成的三维物体的复彩色全息图。数值重建表明，记录的全息图包含物体颜色信息以及来自物体的衍射场信息。
