ABSTRACT:
Optical energy is conveyed through a region and is subsequently converted to electrical energy when it reaches the area of its intended use. Spatially multiplexed laser light is transmitted through an optical fiber to convey the energy through the area. Several light beams or several light beam paths may be used to convey a plurality of beams of light energy into an area either simultaneously or sequentially. Typically, two light beams enter the fiber at different angles of incidence, resulting in a first annulus of laser light that impinges on a first photocell and a second annulus of laser light that impinges on second photocell. This sequence continues alternately with the electrical outputs of the two photocells being coupled to a step-up transformer to provide electrical power for a system of interest, and or the energy being directed to a communication circuit for removing intelligence signals therefrom.
