Abstract
An uncooled thermal matrix detector having a given spectral sensitivity range and being formed from pixels which are thermally insulated from each other, each pixel including an absorbing element which is thermosensitive in the spectral sensitivity range. The thermal matrix detector also includes on its face, turned toward the incident radiation to be detected, of each thermosensitive absorbing element, a biperiodic grating of elementary blocks limiting the viewing angle of the detector, the pitch of the grating being less than the mean wavelength of the spectral sensitivity range. The thermal matrix detector can be applied to so-called BLIP uncooled thermal detectors.
