Reflectors having concave reflecting surfaces (e.g., parabolic reflectors) and electronically controlled beam steering elements are used for rapid, low-diversion, wide-angle, and precision steering of optical beams, including laser beams.
A system, method and apparatus for rapid, large angle, high-precision steering of one or more beams of light, and in particular, laser beams, using one or more concave reflectors to provide narrow, essentially collimated output beams. The rapid, beam steering device amplifies the angular deflection provided by a small angle steering element by means of one or more concave reflecting surfaces while controlling the divergence of the output beam using a divergence control lens, to produce an essentially collimated output beam in a field of regard that subtends +/-45 degrees on one axis and +/-50 degrees on an orthogonal axis.
