Paper Abstract

This paper introduces a new and simple concept of moire effect. A circular grating placed at Talbot planes can achieve beam deflection measurement in real time. It is not only used for 2-D beam shift measurement at every point, but also used to measure the angle and plane parallel degree of optical element and birefringence measurement of the optical material.
