| 摘 要： | 光学元件、结构件的加工和光机系统的装校会导致光学系统的入瞳孔径尺寸和焦距偏离设计值,从而导致光学系统F数的改变,并且光学系统在光谱谱段内成像,光学系统的空间截止频率也在改变.分析了入瞳孔径尺寸D(100～1000mm)、焦距f′(400～2000mm)、F数(4～20)、光谱波长λ(350～800 nm)的变化对光学系...

| Abstract: | Optical component and mechanical component manufacture,and assembling and calibration of optical and mechanical system will result in departure of entrance pupil aperture dimension and focus of optical system from their design value,and change of F number of optical system consequently.In addition,imaging of optical system uses spectrum bands,so spatial cutoff frequency of optical system is also in changing.The influence to optical system MTF on change of entrance pupil aperture dimension D(100~1000mm),focu... |
