红外光学镜头 调制传递函数 刃边扫描法 infrared optical lens modulation transfer function the knife-edge scanning method
摘要
调制传递函数(MTF)是评价红外光学镜头性能的最基本的技术指标之一。对刃边扫描法测量红外光学镜头的MTF进行了研究, 并对f=50 mm, F=1.2波长范围为8～12μm的红外光学镜头的MTF进行了测量。得到了在几个特征频率下的MTF值, 并给出了MTF的曲线图。
Abstract
The modulation transfer function (MTF) is one of the fundamental parameters to evaluate the infrared optical lens. In this paper, the knife-edge scanning method is put forward to evaluate the MTF of infrared optical lens. Then measure the MTF of a infrared lens with f=50 mm, F=1.2 and wavelength=8～12 μm.And MTF is got at several characteristic frequencies. At last the curve of MTF is presented.
