Deformation measurements on antennas under simulated outer space conditions using holographic interferometry
Abstract
A procedure for measuring the deformation of large dish antennas under simulated space conditions with an accuracy of + or - 0.05 mm for a 4 m antenna has been developed and successfully utilized. To assist this method, which uses holographic interferometry, a half-automated procedure for evaluating the interference images has been developed. The test method, test bed, and the evaluation procedure are described, and results of conducted tests are presented.
