Abstract : A mechanical step scanner is provided which moves an image in discrete steps relative to a detector array by displacing, rather than by deflecting, the optical path. The scanner includes first and second rotatable reflector discs that are in optical alignment with each other, with the optical path of the image, and with the detector array. Each reflector disc has a plurality of flat surfaces which are in parallel-spaced relationship (i.e., are 'stepped'); and, the rotation of each disc is at a preselected synchronized speed. This may be used for high resolution high speed tracking.
