The number of defensive and reconnaissance systems requiring infrared focal plane arrays (IRFPAs) has steadily increased over the last few years. These missions require operation of the IRFPAs through nuclear environments both manmade and natural. The Mission Research Corporation Longmire Laboratory was formed to support electro-optic testing of these IRFPAs and other devices such as visible CCDs and FPAs, and IR and visible optical components. Early on, it was found that it would be desirable to possess a real-time analysis capability for all test data collected in the laboratory. Without a real-time, or near real-time analysis capability, a significant amount of resources can be lost collecting large quantities of erroneous data. A real-time capability has yet to be achieved, but a near real-time capability, TDAT (Test Data Analysis Tool) has been developed and has been in use at Longmire Laboratory for the past year. TDAT has been developed entirely in-house in the Borland Delphi programming language. This allows for rapid modifications to the code's capabilities when needed by laboratory users.
