Paper Abstract

In the area of free space optical communications a significant amount of attention has been given to the overall problems of the acquisition and tracking of satellites and the accurate alignment and positioning of optical components on board a spacecraft. Accomplishing these functions with minimal investment in hardware size, weight, and power is essential to the successful evolution of space laser communications (Lasercom). This paper presents two types of nonmechanical laser beam control devices. A nematic liquid crystal (LC) lens and wedge have been fabricated and tested. These electro-optic devices can provide the capability of acquisition, fine tracking, point ahead and alignment of a laser beam in Lasercom terminals. Characteristics such as optical efficiency, switching speed, beam steer range and beam divergence have been measured. Device design and performance parameters are described.
