Scientific paper
The design and performance of an IR FPA test system are described. The parameters, techniques, and equipment required for an IR test system are discussed. An analysis of focal planes is presented to extract the last dB of performance, emphasizing the minimization of required device testing time. The CECOM test system is presented, including the instrument controller, the five source types for characterizing IR FPAs, the electronics, and the protective plexiglass enclosure. Critical test parameters and bias and clocking supply specifications are set forth. Printers which display the results are described, and a buffer/spooler is suggested to increase output rate. Data presentation is discussed. Tests on FPAs and readouts, such as dc uniformity, rms noise, 1/f noise, detectivity, linearity, and responsivity, can be conducted in an automated mode. The possibility of automated testing of optical crosstalk, spectral response, and optical area is mentioned. Future improvements to the facility are listed. Improved yields and increased FPA testing throughput in IRFPA production programs can result from the IRFPA test system facilities.
