NON-MOVING OPTICAL BEAM STEERING USING NON-PIXELATED LIQUID CRYSTAL OPTICAL PHASED ARRAYS

Abstract:

A method for directing light beams includes generating a light beam along a light path. A voltage differential is created by generating a voltage in a first and second linear electrode contacts arranged such that the first and second linear electrical contacts alternate with each other. The light path is altered by passing the light beam through a liquid crystal device coupled to the first and second linear electrical contacts.
