摘要： Optical device comprising: a spatial filter means for eliminating, from the light rays emanating from an observed scene 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 for varying the direction or the restricted range of directions in space in correspondence with which the spatial filter means eliminates said light rays; a spectral dispersion means for imparting to the light rays coming from said spatial filter means a deviation that is dependent on their wavelength; and an image detector for recording the light rays dispersed by said spectral dispersion means, each point on said image detector receiving light rays coming from said scene and having a different wavelength depending on the direction in space from which they come.
