Light source sensing and pointing position-encoded optical proxy

摘要

The present invention is directed to systems, devices and methods utilizing a proxy device that indicates directional aspects of redirected light from a corresponding light redirecting element by the position of one or more redirected light beams in one or more directions or coordinates on such a proxy device. The position characteristics of light redirected from the proxy device correlate to the aim of the light redirecting element associated with the proxy. This allows the proxy information to be used to accurately determine and control the aim of the light redirecting element.
