Paper Abstract

A candidate for IR detectors for third generation thermal imageing systems is the QWIP. ELOP has 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 lpane array that operates simultaneously at the LWIR and NIR. A few aspects of commercializaiton of the QWIP are described focusing on the dark current issue. The QWIP as a multispectral sensor is referred to, especially the sensitivity of the QWIP by means of NETD in comparison with other optional multispectral detectors.
