Abstract

A method is demonstrated for two-dimensional steering of a laser beam by way of the mechanical translation of two phased-arraylike binary optics elements. The elements are translated over a 320-μm distance, resulting in the steering of a green He–Ne laser (λ = 0.543 μm) over a 6-deg field of view. Both theoretical development and experimental verification are presented.
