Método de detección de objetivo de luz incidente redirigida, para la ayuda del control de redirección de luz desde fuentes hacia objetivos, para heliostatos, comprende el uso de un elemento re-direccionador de luz incidente, proveer un conjunto de poxies ópticos asociado con el re-direccionador, observación de la información óptica obtenida de los poxies y el uso de la información; sistema

The present invention relates to apparatus and methods to provide a closed loop pointing system for the purpose of redirecting light from a source onto a target. In one aspect the present invention relates to a method of redirecting incident light, comprising the steps of: using at least one light redirecting element to redirect the incident light; providing a plurality of optical proxies that are associated with the reflecting element in a manner such that at least two of the optical proxies distribute a portion of the incident light uniquely relative to each other, wherein optical information encoded in the light distributed by the optical proxies cumulatively correlates to the aim of the light redirecting element; observing the optical information distributed by the optical proxies; and using the optical information to controllably actuate the light redirecting element in a manner that aims the redirected light onto a target.
