Paper Abstract

We describe a simple method for measuring a long radius of curvature based on the rotatable wedge plate shearing interferometer and a digital moire method. Detailed analysis of the principle of measurement and a description of the experiment are presented. The achievable accuracy of the measurement and the experimental results are discussed.
