Imaging sensor systems address a broad range of needs, in both the military and commercial sectors, and must meet a demanding set of requirements. The unattended imaging sensor application places particularly stressing demands on the technology. Unattended imaging sensors collect data from a broad field of regard, process the information, and transmit it to the observer or to other sensors for integration. The unattended sensor usually operates in a semi-autonomous mode, with a man-in-the-loop only as a check. The sensor must operate over an extended time period, with minimum power, and interpret a large amount of data. Changing environmental conditions impose a further set of requirements. High resolution, high contrast images during one period of the day may degrade significantly as conditions change in the evening, during fog and rain, and as the temperature fluctuates. This paper briefly discusses applications of unattended sensors and highlights recent sensor advances, in several spectral regions, contributing to the unattended sensor application.
