- W2051207667 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. 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 studies and compares two different types of nonmechanical laser beam steering/diverging devices. A nematic liquid crystal phased array has been tested and compared to an acousto-optic Bragg cell. Both electro-optic devices are capable of simultaneous laser beam spoiling and steering which will provide an alternative to the use of electromechanical hardware for acquisition, fine tracking and point ahead in LASERCOM terminals. Characteristics such as optical efficiency, response time, beam steer range and divergence and power consumption have been measured. Device design and performance parameters are described." @default.
