摘要：The optical imaging device comprises, for spectral analysis of a scene, on theone hand a mask (8) arranged in the intermediate image plane (PI), comprising a definednumber of slots which each isolate a defined part of the image of the observed scene, thelarge dimension of the slots being parallel to the lines of elementary detectorsconstituting the detector (11) and perpendicular to the axis (6) of rotation of the mirror(5) and comprises, on the other hand, a dispersive lens (9) arranged in the vicinity of therefocusing lenses (101, 102) and splitting a defined number of wavelengths coming fromthe mask (8), the dispersive lens (9) being designed to disperse each wavelength in adefined respective direction in order to cover the entire sensitive surface of the detector(11) when scanning the scene. The applications are, in particular, for spectral analysis ofthe thermal signature of a target and the detection of gas.
