Abstract
Agile steering of a helium-neon laser beam (?= 632.8 nm) has been demonstrated using a complementary pair of 5-cm-aperture binary optic microlens arrays in the Galilean telescope geometry. Segmentation of a collimated input beam by illuminating approximately 60,000 /5 microlenses of 200-?m diameter and parabolic phase profile results in nearly aberration free beam steering over an 1 1° field of view for ±100- pm lateral displacements of one array relative to the other. Wavefront quality and steering efficiency of the deflected beam has been measured as a function of steering angle and is compared to a simple theoretical model.
