Abstract

The digital Fourier analysis method for optical MTF of IR imaging scanner is described and discussed in this paper. The method obtain the LSF by making use of the scanning function of the scanner itself besides the target slot and reflective collimator as well as the SPRITE detector and its read-out circuit which are practically used in IR image assembling process, and the MTF are calculated by DFT. The method makes a feature of simple equipment, easy operation and quick calculation.
