Abstract
Different configurations of multi-faceted optical elements and associated methods are described that split an input optical beam into multiple output beams, and in a reverse configuration, combine a set of input beams into an output beam. One example multi-faceted optical element includes K optical facets, where K is greater than or equal to six, and K-2 internal surfaces. Each internal surface reflects at least a portion of the incident light and includes a coating designed to modify one or more of a spectral content, polarization, intensity or phase of the incident beam. The multifaceted optical element is configurable to either split an input light beam into four or more output light beams, or to combine four or more input light beams into a single output light beam. Such a multi-faceted optical element can be implemented as part of, for example, a display system, a multi-spectral camera or a polarization camera.
