A spectral rejection device for forming an image on an optical sensor, including means (10) for forming a beam of light rays (14) coming from an observed scene, scanning means (16), means (24) for spectrally dispersing the beam in a direction, at least one mask (26) disposed on the path of the dispersed rays to intercept a narrow band of wavelengths, and means (28) for combining the dispersed rays into a beam of parallel rays focused by a lens (18) onto an optical sensor (20). The invention applies in particular to the spectral analysis of a luminous flux coming from an observed scene.
Dispositif à rejet spectral de formation d'une image sur un capteur optique, comprenant des moyens (10) de formation d'un faisceau de rayons lumineux (14) issu d'une scène observée, des moyens (16) de balayage, des moyens (24) de dispersion spectrale du faisceau dans une direction, au moins un masque (26) interposé sur le trajet des rayons dispersés pour intercepter une bande étroite de longueurs d'onde, et des moyens (28) de recombinaison des rayons dispersés en un faisceau de rayons parallèles focalisés par une lentille (18) sur un capteur optique (20). L'invention s'applique notamment à l'analyse spectrale d'un flux lumineux issu d'une scène observée.
