Abstract
A detector comprising a pyroelectric detector, a temperature control mechanism including a thermoelectric heating/cooling element for keeping the temperature of the pyroelectric detector constant, a temperature sensor, and a temperature controller responsive to the detection signal from the temperature sensor for controlling power supply to the thermoelectric heating/cooling element, and control unit provided within the temperature controller for pyroelectric detector. Synchronizing the operation of the pyroelectric detector and the thermoelectric heating/cooling element such that the power supply of the thermoelectric heating/cooling element is turned on and off only when data is not being collected by the pyroelectric detector.
