Computer-Generated Holography (abbreviated as CGH) is a key technology in modern optics, which generates holograms for displaying three-dimensional images through digital computation. With the development of computer science, optical engineering, and display technology, CGH has shown broad application prospects and research value in numerous fields such as data storage, three-dimensional display, optical testing, optical communication, and information security. This article will provide a detailed introduction to CGH from aspects such as its basic principles, computational methods, implementation technologies, and application prospects.

Film photomasks play a vital role in modern optical production, semiconductor patterning, PCB development, and various micro-fabrication processes. They serve as high-precision pattern carriers, enabling accurate light-based imaging or etching on different substrates. In this article, I will explain how a Film Photomask works, why it is important, and what technical parameters make our solutions from Ningbo Zhixing Optical Technology Co., Ltd. reliable. Clear structure, easy-to-read language, and professional depth are maintained throughout.

In the fast-evolving field of optical metrology, CGH Cylinder Nulls have emerged as indispensable tools for precision testing and calibration of cylindrical and aspheric surfaces. By replacing complex mechanical setups with computer-generated holography (CGH), these null correctors enable ultra-precise surface verification in high-end optical systems such as telescopes, camera lenses, and semiconductor inspection instruments. This article explores how, why, and what makes CGH Cylinder Nulls vital for industries seeking sub-micron accuracy and cost-effective testing solutions, while also highlighting the professional excellence of Ningbo Zhixing Optical Technology Co., Ltd., a leading manufacturer in this field.

CGH Null Correctors (Computer-Generated Hologram Null Correctors) are advanced optical testing devices used to measure and correct aberrations in precision optical systems, such as aspheric and freeform lenses or mirrors.
