Optical system for control of antenna mirror shape

Abstract

The possibilities of optical triangulation method (triangle method) for investigation of antenna mirror shape are analyzed. It is shown that developed by the authors method of optical triangulation with the variable measuring base reduces the requirements for measurement accuracy by replacing a part angular measurements by linear ones. On the basis of the method the scheme of optical device is designed, the working model is constructed and its experimental testing is carried out. The obtained results proved that the developed method and scheme of the optical device make it possible to control the mirror surface shape with the necessary in antenna engineering accuracy.
