Abstract
The use of spatial light modulators to steer light beams and/or vary a field of view is disclosed. A dual frequency liquid crystal spatial light modulator can be controlled so as to form a blazed phase grating thereon that effects desire deflection of incident light. A dual frequency liquid crystal spatial light modulator can also be controlled so as to communicate light from a desired field of view to an imaging device or the like.
