AB - Testing of scanned linear infrared detector arrays, particularly in a developmental environment, can be facilitated through the use of Common Module FLIR (forward-looking infrared) equipment. The modular nature of these FLIRs allows rapid exchange of detector/Dewar modules, however, the cost of Common Module Dewars can become excessive if many arrays are tested. It is desirable to utilize a reusable Dewar, but the problem of quick and reliable multiple electrical connections to the array must be solved. We have designed and fabricated a reusable Dewar, which maintains the Common Module detector/Dewar envelope with a minor exception, in which the arrays can be quickly mounted and dismounted with little effort and limited expertise. In the described version, 148 electrical connections are automatically completed when the array is fastened in place on the cryogenic thermal sink. Interchangeable radiation shielding and cold filtering is also easily accomplished in the same operation. After evacuation through a valve, the Dewar mounts quickly in the Common Module FLIR for laboratory and field testing with standard Common Module cryogenic coolers. The interconnection is also adaptable to integral cooler Dewars where the detectors are mounted directly on the cryogenic generator.
