Abstract: A spectral rejection device for forming an image on an optical sensor, including a system for forming a beam of light rays coming from an observed scene, a scanning system, a system for spectrally dispersing the beam in a direction, at least one mask disposed on the path of the dispersed rays to intercept a narrow band of wavelengths, and a system for combining the dispersed rays into a beam of parallel rays focused by a lens onto an optical sensor. The invention applies in particular to the spectral analysis of a luminous flux coming from an observed scene.
