Abstract

A pyrodetector, which is both movement selective and directional selective, has preferably a foil supporting detector elements relative to a concave mirror which may have a spherical curve surface, a spherical-parabolic curve surface or a curve surface between a spherical surface and a spherical-parabolic surface. The sensor is preferably a plurality of individual sensor elements which are arranged on an arc, preferably on a planar member or a foil, and may include additional or second sensor elements having electrodes which are for determining temperature compensation for the detector.
