Abstract
A system for variable distribution of light is provided. The system comprises: a plurality of reflective optical devices having a first variable reflective beam splitter configured to receive light along an input light path and direct a first portion of the light along a first light path and direct a second portion of the light to another one of the plurality of reflective optical devices, and a last reflective optical device configured to receive remaining light from a second last reflective optical device and to perform one of: direct the remaining light along a last light path; and, divide the remaining light into two portions, and direct the two portions along two different light paths. At least one optical property of one or more of the plurality reflective optical devices is adjustable to variably apportion received light.
