Abstract
A reticulated pyroelectric target, for the detection of infra red radiation, comprising a plurality of closely packed islands of pyroelectric material separated by a plurality of relatively narrow grooves in which in order to physically strengthen the target the islands and grooves are so shaped that the grooves do not form a straight line over any appreciable portion of the target surface. Preferably the islands are hexagonal to provide a good packing density.
