Abstract

Santa Barbara Research Center (SBRC) is actively involved in the design, fabrication, and evaluation of infrared detector arrays, both linear and two-dimensional. The large scale production of 64x64 HgCdTe arrays requires that testing be accomplished quickly and with minimum operator interaction. The optical components of the test set described provide stimuli to measure over eight detector parameters, including 2-dimensional Modulation Transfer Function (MTF), with a test time of only a few minutes. The optical design stresses the fundamental radiometry for each test while accounting for, and minimizing, the contributions from unwanted, but mostly controlled, background sources.
