A method is introduced for testing stray light coefficient, vignetting coefficient and image surface uniformity opticalsystem with largeaperture and long focal length.
叙述一种用于测试大口径、长焦距光学系统杂光系数、渐晕系数、像面照度均匀性等光学参数的检测方法。

The system can be set up and adjusted quite easily and used to test large-apertureoptical elements without high quality reference optics of the same size.
该系统结构简单，调整方便，并可以用作检验大口径光学元件而勿需同样尺寸的高质量参考光学件。

To isolate the retroreflections from the target and the self-oscillation in multipass amplifier system, the large-aperture electro-optical switch is required.
