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.

Heat detector with a limited angle of vision

An infrared imaging device including a quantum device positioned and configured to detect infrared transmission at ambient temperature, a cooler thermally coupled to the quantum device, and controller for controlling the cooler based on a function of plural image-taking parameters as a command.
