Method for measuring dihedral angles of a cube-corner retroreflector having curved mirror surfaces

Atsushi Minato

Abstract

Measurement of dihedral angles of a cube-corner retroreflector with curved surfaces is discussed. A simple method for measuring a dihedral angle from an interferogram is given based on theoretical consideration. A general method to obtain three dihedral angles by means of least-squares fitting of the interference fringes is also described. The method is tested by means of simulation data.
