ABSTRACT:
A pyroelectric detector element having defined on a major surface two spaced areas exhibiting radiation absorbing and/or reflecting properties. A mirror-like area comprising a dielectric material is provided in at least part of the space, and preferably extends over all or substantially all of the space, defined between the two spaced areas to reflect the radiation and provide a substantially nil output contribution for the radiation falling on the space.
