The development of a compact and high performance MWIR step zoom camera based on the 640x480 staring focal plane array (FPA) is described. The camera has a 20 magnification step zoom ranging between 24°x20° for the wide field of view up to 1.2° x 1° for the narrow field of view and an aperture of F#4. The processing electronics is based on a flexible and expandable architecture. Special emphasis is spent on the solutions adopted for the design of this high zoom ratio and fast optics FLIR and on the electronic architecture and algorithms for image processing. An overview of the performance is given.
