Optical design of hollow cube-corner retroreflector for space

We discuss the design of next generation hollow satellite retroreflectors for satellite laser ranging and atmospheric measurements. We also review a method for controlling the beam pattern of the reflection using curved mirrors in the retroreflector, and this method is applied to the design of both single-element and four-element satellite retroreflectors. The concept of the acute angle retroreflector and possible applications to a satellite retroreflector are also discussed.
