Abstract

This paper describes the successful completion of a long wavelength second generation infrared camera which was designed, fabricated and tested at Kolisman Co. The design focused on a low cost approach based on state-of-the art components which were sufficiently mature in their development cycle to be readily available if no design modifications were necessary (i.e. 'off the shelf'). The system design approach for the sensor package allows for retrofit to existing sensor platforms thereby reducing integration costs while offering second generation performance. The design is based on a 7.5-10.7 micron long wavelength focal plane array (FPA) consisting of 240 x 4 elements. Cryogenic cooling is supplied for the array using a state-of-the-art linear drive Stirling cycle refrigerator. The system is a parallel scanned type utilizing on-focal plane time delay and integration to achieve improved signal to noise ratio. Digital scan conversion is used to obtain RS-170 TV compatible output.
