Abstract
2-D Optical Phased Array (OPA) antenna based on a Liquid Crystal On Silicon (LCoS) device can be considered for use in free space optical communication as an active beam controlling device. Several examples of the functionality of the device include: beam steering in horizontal and elevation direction; high resolution wavefront compensation in large telescope; beam shaping with computer generated kinoform. Various issues related to the diffraction efficiency, steering range, steering accuracy as well as magnitude of wavefront compensation is discussed.
