ABSTRACT:
Mercuric iodide detector systems are made less power consumptive and smaller by employing a single Peltier cooler rather than the two required by prior art systems. The optimal temperature requirements (and thus leakage current conditions) for the two critical temperature sensitive components for such a system are met by cooling the components to a reference temperature using a single cooler and by illuminating the detector to achieve the required operating performance. The elimination of the extra cooler not only conserves power and reduces maintenance requirements, but also reduces size. The use of light to achieve the required detector and FET leakage current relation for optimum operation is permitted by the implementation of a feedback loop for automatic control of the operation.
