随着现代工业技术的迅速发展,光学系统应用的范围也日益扩大,光学仪器和电子学的结合,要求对光学系统现有的象质概念和检测方法赋予更确切的含义和有效的方法。评价象质的更臻完善的判据理论(例如光学传递函数和刃边曲线等测试法)业已提出而且得到很快的发展。目前光学系统在光电仪器中的传递性能,对整个仪器的性能具有决定性的影响。代替过去物镜—感光层、物镜—目镜—眼睛系统而出现物镜—电视显象管、光电倍增管、光电变换器以及其它各类接收器。因此用目视测量或照相检验物镜象质,显然已不能适应现代要求,引用光电测试法势在必行。尤其是对评价物镜的传递性能来说,光学仪器质量最通用的判据—仅仅测量分辨率—已经显得不足,需要能全面反映图象质量的更为充分的信息。
With the rapid development of modern industrial technology, the scope of application of optical systems is also expanding. The combination of optical instruments and electronics requires more precise meaning and effective methods for the existing concepts and detection methods of optical systems. More sophisticated criteria for evaluating quality (eg, test methods such as optical transfer functions and edge curves) have been proposed and developed rapidly. The current optical system in optoelectronic devices in the transfer performance, the performance of the entire instrument has a decisive impact. Instead of the objective lens - the photosensitive layer, the objective lens - the eyepiece - the eye system and the emergence of the objective lens - TV kinescope, photomultiplier tubes, photoelectric converters and other types of receivers. Therefore, with the visual measurement or photographic test lens quality, apparently can not meet the modern requirements, the reference photoelectric test is imperative. In particular, the most common criterion for measuring the quality of optical instruments, which measures the resolution of the optics, is insufficient to evaluate the transmission performance of the objective and requires more adequate information to fully reflect the quality of the image.
