ABSTRACT:
Coherent light from a laser is directed through first and second two dimensional planar arrays of lenslets which are moved relative to each other to enable the beam to point along any diffraction order, and fine pointing of the beam between orders is accomplished by slightly changing the angle of incidence of the beam with respect to the arrays. The laser is replaced by a photoreceptor when the scanner operates as a light beam receiver.
