ABSTRACT:
A target illuminating system is provided for steering a scan optical beam and reducing the size of an optical output aperture. The system includes an array of scan beam outlets being selectively operative to receive and project a point source of scan beam radiation along an optical path. The system also includes a collimating element being disposed along the optical path. The collimating element is operative to receive the point source of scan beam radiation and to output the collimated scan optical beam in a desired coarse direction corresponding to a selected one of the scan beam outlets. The scan optical beam defines a scan exit pupil which is substantially coincident with the optical output aperture.
