Imaging Infrared Detectors II

Abstract : JASON has been tasked by the Army to review recent progress in infrared detector technology and to update the earlier JASON report "Imaging Infrared Detectors" (JSR-91-600). To this end, a workshop was conducted during the 1997 Summer Study with distinguished participants drawn from industry, academia, and government, listed in Appendix D. Through discussions with workshop participants and the JASONs an updated overview of the state of imaging infrared detector technology was developed, and is presented in the body of this report as follows: Section 2 (Image Character); Section 3 (Uncooled Microbolometer Arrays); Section 4 (Quantum Well Infrared Photo detectors); Section 5 (HgCdTe Photodetector Arrays); and Section 6 (New Developments). Appendices to the original report contained primers on infrared basics, which have been proven to be useful. The current report contains updated versions: Appendix A (Fundamentals of IR Detector Performance); Appendix B (Imaging Bolometer Arrays); and a new addition, Appendix C (Thermoelectric Materials).
