Paper Abstract

Optical Phased Array technology promises to reduce the size, weight, and power consumption of optical pointing and steering systems by replacing complex mechanically gimballed mirrors with small, lightweight, nonmechanical devices. This paper develops and describes several diagnostic techniques that can be used to evaluate the performance of Optical Phased Arrays (OPAs) and demonstrates their use by applying them to the evaluation of a commercially available liquid crystal device. Finally, the operation of this device is demonstrated by integrating it into a steered imaging system.
