Optical device comprising: a spatial filter means (FS) for eliminating, from the light rays emanating from an observed scene (1) those coming from a direction or restricted range of directions in space, while letting through most of the light rays coming from said scene; means (21) for varying the direction or the restricted range of directions in space in correspondence with which the spatial filter means (FS) eliminates said light rays; a spectral dispersion means (26) for imparting to the light rays coming from said spatial filter means (FS) a deviation that is dependent on their wavelength; and an image detector (28) for recording the light rays dispersed by said spectral dispersion means (26), each point on said image detector (28) receiving light rays coming from said scene (1) and having a different wavelength depending on the direction in space from which they come.
Dispositif optique comportant : un moyen de filtrage spatial (FS) pour éliminer, parmi les rayons lumineux issus d'une scène (1) observée, ceux qui proviennent d'une direction ou une plage restreinte de directions de l'espace, tout en laissant passer la plus grande partie des rayons lumineux issus de ladite scène ; des moyens (21) pour faire varier la direction ou la plage restreinte de directions de l'espace en correspondance de laquelle le moyen de filtrage spatial (FS) élimine lesdits rayons lumineux ; un moyen de dispersion spectrale (26) pour impartir aux rayons lumineux issus dudit moyen de filtrage spatial (FS) une déviation dépendante de leur longueur d'onde ; et un détecteur d'image (28) pour enregistrer les rayons lumineux dispersés par ledit moyen de dispersion spectrale (26), chaque point dudit détecteur d'image (28) recevant des rayons lumineux issus de ladite scène (1) et présentant une longueur d'onde différente en fonction de la direction de l'espace de laquelle ils proviennent.
