Although the performance of self scanned arrays would be increased if they were cooled, there are applications where this increased performance may not be required. However, there are applications where self scanned arrays must be cooled to provide the required performance. Typical applications that require low temperature cooling are low light level, long time stare applications; and cameras where dark spots must be held to a minimum. Low temperatures in the range of -40°C to -50°C are ideal for thermoelectrically cooled self scanned arrays. A thermoelectric heat pump is a small, solid state, efficient method of cooling self scanned arrays. A typical system consisting of an enclosure and thermo-electric heat pump is described.
