Method for extracting optical energy from an optical beam

摘要

A method includes generating a primary beam using light emitted by a light-source. The method includes generating a secondary beam using a portion of the light using a lens of a telescope. The lens includes one or more refraction elements positioned on a first surface of the lens, and the secondary beam is generated by diverting the portion of the light using the one or more refraction elements.

1. An apparatus comprising:
a primary mirror; a secondary mirror; and a lens comprising a refraction portion surrounded by a substantially planar portion, wherein the substantially planar portion, the primary mirror, and the secondary mirror are arranged to generate a primary beam using a first portion of light emitted from a light-source, and wherein the refraction portion is arranged to generate a beacon beam using a second portion of the light emitted from the light-source.
