<p>The invention is an optical system, which simultaneously captures two images of a scene. The system has no moving parts and each image has a different field of view. The system of the invention comprises a dichroic filter, a single detector, and additional optical elements. The dichroic filter divides the light entering the system into a first spectral range and a second spectral range. The additional optical elements focus the light that enters the system onto the planar surface of the detector, which has a surface comprising a matrix of pixels, each of which comprises at least two subpixels. One of the subpixels is sensitive to light in the first spectral range and the other is sensitive to light in the second spectral range. The first image is captured on the set of subpixels sensitive to the first spectral range and the second image is simultaneously captured on the other set of subpixels.</p> |
