Abstract
A pyroelectric detector comprises an element (1) of pyroelectric material that responds to variations with time in the intensity of radiation incident on an operative surface region of the detector much larger than the area of a major face of the element (1). The Noise Equivalent Power of the detector is improved by providing a thermal diffusion means (10) to conduct thermal energy to the element from remote parts of the region. The element is resiliently supported on one or more flexible films (2,3) and the thermal diffusion means (10) is a thermally conductive layer on a film (3).
