Abstract

“Two-dimensional grating and two-camera method” has been validated to measure areal relative displacements of curved surface of structural shape. A parabolic antenna of 1.5m in diameter has been measured by only one shot of photograph for the purpose of correction of reflector error, in order to develop a high accurate antenna system. The effectiveness of the proposed measurement method for a large and precise curved surface has been verified.
