摘要/Abstract

摘要： 描述成像光谱仪系统空间分辩率优劣的关键参数是系统的调制传递函数-MTF,MTF的检测是一个古老而又困难的课题。首次在有限视场的输入景物下通过移动刀刃法对扫描成像过程中垂直扫描方向系统像方MTF的检测进行了分析和模拟计算。

Abstract: The key parameter which describes the spatial resolution of imaging spectrum system is the modulation transfer function (MTF), it is an old and difficult topic to measure the MTF. Under the input scenery with finite visual field, the analyses and simulative calculation of the image-side OTF of vertical direction of the scanning image by moving blade have been done firstly.

Key words: method of moving blade, image-side MTF, imaging spectrum system, optical disturbance
