Title
(EN) SYSTEM FOR OPTICAL WIRELESS POWER SUPPLY
(FR) SYSTÈME POUR ALIMENTATION ÉLECTRIQUE OPTIQUE SANS FIL
Abstract
(EN)
A system incorporating safety features, for optical power transmission to receivers, comprising an optical resonator having end reflectors and a gain medium, a driver supplying power to the gain medium, and controlling its small signal gain, a beam steering apparatus and a controller to control at least the beam steering apparatus and the driver. The controller responds to a safety risk occurring in the system, by outputting a command to change at least some of the small signal gain of the gain medium, the radiance of the optical beam, the power supplied by the driver, the scan speed or the scan direction and position of the beam steering apparatus, or to register the scan pose which defines the location of said optical-to-electrical power converter. The controller may also ensure a high overall radiance efficiency, and may warn of transmitted power not received by a targeted receiver.

Cette invention concerne un système qui comprend des éléments de sécurité pour une transmission de puissance optique à des récepteurs, comprenant un résonateur optique possédant des réflecteurs d'extrémité et un milieu à gain, un pilote fournissant de la puissance au milieu à gain, et commandant son gain en petits signaux, un appareil de guidage de faisceau et un dispositif de commande pour commander au moins l'appareil de guidage de faisceau et le pilote. Le dispositif de commande répond à un risque de sécurité se produisant dans le système en émettant une instruction pour modifier au moins une partie du gain en petits signaux du milieu à gain, de la luminance du faisceau optique, de la puissance fournie par le pilote, de la vitesse de balayage ou de la direction de balayage et de la position de l'appareil de guidage de faisceau, ou pour enregistrer la position et l'orientation du balayage qui définissent l'emplacement dudit convertisseur de puissance optique-vers-électrique. Le dispositif de commande peut également assurer un haut rendement de luminance totale, et peut avertir de la non réception du courant transmis par un récepteur cible.
