ABSTRACT:
A pyroelectric infrared detector of the dual element type has its two elements connected in parallel but with opposite polarities. The dual elements are arranged such that the detector element outputs may be taken out from only one side of the pyroelectric material used to form the detector. The detector utilizes supplementary elements which are insensitive to infrared radiation and interconnecting members to connect the supplementary elements to the detector elements so as to enable the interconnection of the dual parallel elements with opposite polarities to external circuitry by wires connected to only a single side of the pyroelectric material.
