Abstract

Infrared detector focal plane arrays made from platinum silicide (PtSi) are currently being used in applications where good reliability, low cost, and high producibility are required. Future use of these sensors in extreme operating environments has also been suggested. We have tested small arrays of detectors in constant acceleration environments up to 300,000 times that of gravity, and in dynamically changing acceleration stress up to 5000 g/sec. Measurements of both the optical and electrical performance of the detectors were taken after acceleration. Our measurements show that there are no changes in the infrared spectral characteristics of the samples subject to either transient or steady state acceleration up to 300,000 g. The only changes noted in the samples were found from electrical measurements where excess dark current was noted at static accelerations greater than 200,000 g. Our results show that platinum silicide should be an excellent candidate for applications which anticipate large static and dynamic acceleration stresses. Detailed experimental data is presented.
