| Abstract: | MRTD is an important parameter for assessing performance of complete thermal imaging system.In this paper,subjective and objective methods for measuring MRTD of thermal imaging system are discussed and the working principle and measurement procedure of objective measurement method of MRTD (video signal MTF method and photometric method)are described in detail.This paper compares the advantage and disadvantage between the two kinds of measurement methods and points out that the objective method for measuring MRTD of thermal imaging.system is very important to assess the performance of complete thermal imaging system. |
