Electronic Laser Beam Scan with a Switched Focal Array

A laser beam will be totally electronically scanned among any number of discrete angular positions within a nearly 180 degree sector by exciting an array of elements disposed over the focal surface of a lens or reflector through a set of controlled switches. Feasibility of the proposed switched array will be established through fabrication and test of a prototype. The configuration of objective and focal plane array of guide elements will be modeled analytically to arrive at a design which optimizes the preformance-potential inherent in the proposed configuration and new technology. Phase I experimental and Phase II through design and fabrication of a full prototype electronic scan laser system. High speed electronic scan will enable realization of volumetric search and track-while-scan LIDAR systems. Optical electronic switches integrated with compatible focal surface arrays may find use in display and computer applications.
