Paper Abstract

A new method of precisely measuring the radius of curvature of the divergent spherical and cylindrical wavefront of a laser beam is presented by the use of a holographic grating and an optical system, the measuring accuracy is analyzed and some measures of improving the result are given. Finally, the possibility of measuring the distortion aberration of an optical system by the use of a non-linear holographic grating is also discussed.
