近年来,人们把电子学通信系统的频率过滤理论引深到光学成象系统,用来评定和检验成象质量的问题。用光学传递函数(OTF)或光学调制函数(MTF)来评定光学系统或镜头的质量就是基于这种理论发展起来的一种新的测量技术。这种测量手段能准确、迅速评定光学系统的优劣,在经济发达国家已应用到现代光学工业,特别是照相机工业中。光学传递函数对产品设计、加
In recent years, people have introduced the theory of frequency filtering in electronic communication systems to optical imaging systems to assess and test the imaging quality issues. Using optical transfer function (OTF) or optical modulation function (MTF) to evaluate the quality of an optical system or lens is a new measurement technique developed based on this theory. This measure can accurately and quickly assess the pros and cons of optical systems in the economically developed countries have been applied to the modern optical industry, especially the camera industry. Optical transfer function of product design, plus
