ABSTRACT:
The specification describes a novel pyroelectric detector in which one input detector electrode is mounted directly on one surface of a pyroelectric substrate and is used for absorbing chopped incoming infrared radiation. The output detector electrodes are capacitively coupled to the reverse substrate surface and provide an AC coupled output signal with a minimum of conductive heat transfer from the pyroelectric substrate.
