Abstract

The use of a retroreflector is described for co-alignment of two optical beams that are collimated but propagating in opposite directions. This method is applicable to any optical system that requires precise pointing, such as laser-ranging and tracking systems. The application illustrated here is star acquisition in long-baseline stellar interferometry.
