Abstract
A variable optical device for controlling the propagation of light has a body of liquid crystal optical material with a center and a periphery, a heating system including an electrically controllable heat source and a thermal radiator arranged at the periphery for cooling a portion of the body of material. The heating system is operative to generate a spatially modulated temperature gradient and to provide a desired light propagation behavior.
