| 摘 要： | 大口径可见光到红外波段OTF测试仪测量功能齐全 ,即可测量照相系统、望远系统的光学传递函数 (OTF) ,并且兼有测量焦距、放大率和光谱透射比等参数的功能。通过用OTF标准镜头进行标定 ,开展OTF国际比对工作 ,为建立OTF计量标准打下基础。该系统测量不确定度为 :可见光至近红外波段 :轴上 0 0 3、轴外 0 0 5 ;红外波段 :轴上0 0 4、轴外 0 0 6。重复性 :0 0 1(RMS)。主要性能指标均达到当前国际先进水平。

| Abstract: | The equipment provided with all necessary function of testing,not only can measure the OTF of camera and afocal system, but also measure focal length, angular magnification and transmission and so on By measurement the OTF standard lens were calibrated, the OTF international comparison work was done, laying a foundation the OTF metrology standard was established The equipment uncertainty measurement of MTF is on axis 0 03, off axis: 0 05 from visible to near infrared; on axis: 0 04, off axis: 0 06 in infrared The repeatability of the system is 0 01(RMS) And important performance of the system reach international advanced level at present |
