Abstract: In this paper we highlight some of the advantages of lightweight beam steerers that can be employed at or near the entrance aperture of the system. One advantage of such an implementation is reduced field aberrations. The effect of the choice of beam steerer location on image quality is quantified. A specific example of the use of agile beam steerers in a laser radar system is considered. Configurations are described that allow continuous angular coverage. The effect of steering efficiency is discussed. !8
