title: Multiple channel interferometer for metrology.
abstract: A multiple channel interferometer was developed and used for the remote monitoring of the dynamic behavior of a large-diameter antenna experiencing simulated solar irradiance in a space simulation chamber. Reversible fringe-counting techniques were employed to measure changes in the distance between the equipment located outside the chamber and each of seven optical retroreflectors mounted on the face of the antenna. After the initial measurement program was completed, the equipment was modified to improve its performance.
