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.
