ABSTRACT:
In accordance with the teachings of the present invention, a system and method are provided for steering a beam of optical radiation. The system includes a dividing telescope microlens array for receiving a beam of optical radiation directed along a first path and dividing the beam into a plurality of divided beam columns. A steering microlens array collectively redirects each of the divided beams along a second path. The system further includes a compensation lens for compensating for phase differences which may otherwise exist among the redirected divided beam columns. The redirected divided beams are then combined by way of a combining microlens array to provide a recombined far-field beam of optical radiation directed along the second path.
