| Zusammenfassung: | To provide an optical power supply system capable of efficiently supplying power to a distant light receiver.SOLUTION: An optical power supply system includes a laser light source, a light projector that projects a laser beam output from the laser light source toward a photoreceptor positioned far away and performing photoelectric conversion, and an adjustment mechanism that adjusts the light intensity distribution of the laser light projected onto the photoreceptor. The laser light source includes a plurality of laser devices, and the adjustment mechanism includes a delivery fiber, and an optical concentrator that inputs the laser light output from each of the laser devices into the delivery fiber.SELECTED DRAWING: Figure 1
【課題】遠方の受光器に効率的に給電を行うことができる光給電システムを提供すること。【解決手段】光給電システムは、レーザ光源と、遠方に位置して光電変換を行う受光体に向かって、前記レーザ光源から出力されたレーザ光を投光する投光器と、前記受光体に投光されるレーザ光の光強度分布を調整する調整機構と、を備える。前記レーザ光源は、複数のレーザ装置を有し、前記調整機構は、デリバリファイバと、前記レーザ装置のそれぞれから出力されたレーザ光を前記デリバリファイバに入力させる光集約器と、を有してもよい。【選択図】図１ |
