Zhixing, would like to provide you high-quality Computer Generated Hologram (CGH). Computer Generated Hologram (CGH) is a kind of image processing technology based on optical principles. Through interference, diffraction, refraction, and other phenomena of light, the information of the object is recorded in the optical medium, forming an optical recording method, that can realize the reproduction and enhancement of the image, and has a very wide application prospect.
The production process of Computer Generated Hologram (CGH) is mainly divided into two steps: recording and reproduction. In the recording process, a beam of reference light and a beam of object light are illuminated on the recording medium, and a special interference pattern is formed because the object light interferes with the reference light. In the reproduction process, the two beams of light are again used to illuminate the recording medium, and the image of the original object can be reproduced.
Different from traditional planar images, Computer Generated Holograms (CGH) can record and reproduce three-dimensional information and can realize the operation of spatial reproduction, magnification, and rotation of images, to accurately restore the shape and details of objects. Therefore, computer-generated holograms (CGH) are widely used in many fields such as image storage, 3D imaging, optical computing, and information security.
It is worth mentioning that Computer Generated Hologram (CGH) has a wide range of applications in medical image processing, object morphology analysis, image encryption transmission, and other fields. For example, in medical imaging, more clear three-dimensional body images can be obtained through hologram technology, which is conducive to the diagnosis and treatment of diseases. In object shape analysis, holograms can accurately restore the shape and center of gravity of the object, and provide an effective means for object mass measurement and motion tracking. In image encryption transmission, hologram technology can realize multi-level encryption and improve communication security.
Therefore, it can be seen that Computer Generated Hologram (CGH) as a very advanced image processing technology has important application significance and development prospects. It is believed that shortly, with the continuous progress of technology and the deepening of application, optical computational holograms will certainly bring more convenience and innovation to our production, scientific research, and life.
