Paper Abstract

Spectral selection is a powerful technique for enhancing standard infrared imaging systems that have sensitivity over a broad range of the infrared spectrum. The uses of enhanced systems include imaging objects that typically appear transparent to a standard broadband IR imaging system, or to image through materials that would typically appear opaque. Spectral selection can also be used to detect the presence of various chemical species, and to measure their concentration in the atmosphere, or in liquid and solid materials. Spectral selection can be achieved through the use of filters or through the use of a filtered illumination source. This paper briefly describes various applications for imaging cameras based on InGaAs, InSb, and QWIP focal plane arrays in conjunction with filters that are both fixed and tunable.
