ABSTRACT:
An infrared radiation detector comprises two differentially connected pyroelectric detector elements in parallel-opposition. The detector elements are formed in a single body of pyroelectric material having two adjacent pairs of overlapping electrodes on opposite major surfaces of the body. The two detector elements are poled in the same direction. To electrically connect the top electrodes of each pair to the bottom electrodes of the other pair, each electrode is provided with an L-shaped extension. Each extension is arranged such that at an edge of the body the extension of the top electrode of one pair overlaps the extension of the bottom electrode of the other pair. The overlapping extensions can be electrically connected together by conductive epoxy or by conductive clips on the edge of the body.
