非相干成象系统的光学传递函数(OTF)描写了衍射和除畸变以外的各种象差对成象的影响。OTF的测量已被普遍认为是检验光学系统成象质量的主要项目。根据OTF制订的质量指标已经开始应用于照相物镜,电视、电影摄影物镜、航摄物镜等各类成象光学系统,评价设计结果,控制产品质量。光学传递函数理论从40年代开始提出,经过 The optical transfer function (OTF) of an incoherent imaging system describes the effects of diffraction and aberrations other than distortion on the imaging. The measurement of OTF has generally been regarded as the main item that examines the imaging quality of optical systems. According to OTF quality indicators have been developed for photographic objectives, television, film photography objectives, aerial photography and other imaging optical systems, evaluation of design results, control of product quality. The theory of optical transfer function was proposed from the 1940s through
