A method and apparatus for providing a pyroelectric detector with stray capacitance reducing shielding is disclosed herein. In order to minimize stray capacitance of the detector, the housing of the detector is coupled to the output of the detector output signal amplifier through a suitable feedback network to maintain the housing at output signal potential. The capacitive impedance between the housing and the various electrical leads is then apparently infinite.
