Research output: Contribution to journalConference articlepeer-review

Abstract

A candidate for IR detectors for third generation thermal Imaging systems is the QWIP (Quantum Well Infrared Photodetector). ELOP has been gone through five years of development and evaluation of QWIP focal plane arrays and QWIP based thermal imaging system as a technology demonstrator. The R&D results are 320×256 QWIP based thermal imaging system operating in the 8-10μm band and a QWIP focal plane array that operates simultaneously at the LWIR and NIR. A few aspects of commercialization of the QWIP are described focusing on the dark current issue. The QWIP as a multispecral sensor is referred too, especially the sensitivity of the QWIP by means of NETD in comparison with other optional multispecral detectors.
