Abstract

The present invention is directed to an optical beam deflection system (10) and includes a substrate (12) having a plurality of spaced electro-optic scanning devices (14) disposed thereon. These electro-optic scanning devices (14) are capable of deflecting an optical beam (16) in response to electrical control signals. The optical beam (16) passes through all of the scanning devices (14). Electrical leads (18) are used to communicate electrical control signals individually to each scanning device (14), and a controller (20) selects and applies these electrical control signals to the scanning devices (14) through the electrical leads (18).
