Optical beam steering devices having polygonal reflectors therein

Abstract

An optical beam steering device includes an at least partially optically transparent container having a polygonal reflector therein that is at least partially surrounded within the container by an optically transparent liquid. The polygonal reflector may be configured to have a center of mass, which is equivalent to its geometric center. In addition, the polygonal reflector may be configured so that a difference between an effective density of the polygonal reflector and a density of the optically transparent liquid is preferably less than about 2.1 grams per cubic centimeter. More preferably, the polygonal reflector and the optically transparent liquid may be collectively configured to be neutrally buoyant relative to each other within the container.
