Two dimensional thermal imaging arrays-a low visibility navigation aid

Infrared imaging in the medium wavelength range (10-14 /spl mu/m), corresponding to the thermal blackbody maximum near room temperature and to the atmospheric window, is desirable for a wide range of applications. Night vision, target recognition, reconnaissance, driving aids, and navigation in foggy and poor visibility weather are among the applications of this technology. Recent advances in pyroelectric imaging have made it possible to produce compact, low-cost, uncooled infrared cameras that are capable of delivering television quality images.
