Abstract
The unique properties of quadratic lead lanthanum zirconate titanate (PLZT) compositions make feasible the development of phased array optical scanners. Two implementations of integrated PLZT phased array scanners as two-port and three-port devices are presented. The three-port offers a significant reduction in the maximum electrode voltage required to effect a specific scan angle. The maximum electrode voltage of the PLZT phased array scanner is characterized in terms of the resolution of the scanner.
