Abstract

The development of a compact and high performance MWIR zoom camera based on the 320 X 240 staring focal plane array (FPA) is described. The camera has 20 magnification zoom optics with the maximum 40°x 30° of super wide field of view and 7.6 cycles/mrad of resolving power with the operation of attached microscanning system. In order to correct non-uniformities of detector arrays, we have proposed the multi-point correction method using the defocusing technique of the optics and acquired the highest quality images. The MRTD of our system shows good results below 0.05 °K at spatial frequency 1 cycles/mrad at narrow field of view.
