Abstract
In this paper we present a novel approach for dynamic wavefront generatio based on reconfigurable Opto-VLSI processing. Computer algorithms are developed to generate arbitrary quadric-phse lense and lenslet array with programmable focal lenght, beam steering and lens diameter by driving the Opto-VLSI processor with different computer generated phase holograms. Proff-of-concept experimental results show that multiple spheric and aspheric lens/lenslet wavefrongs can be generated with each lens independently addressed. The measured meaximum focal length tuning range is from +80mm to infinity and the beam scanning angular range is +7mrad, which are in excellent agreement with theory. Difference spatial profiles for wavefront correction are also experimentally demonstrated.
