Computational method using finite element theory for analyzing 2-D lateral shearing interferograms

Yucong Zhu

Open Access Open Access

Abstract

A lateral shearing interferogram can be expressed by the following differential equation Using finite element theory, we can construct a triangle-wave function at the sample points of the wavefront: where hi = x = xi − xi−1.
