Abstract

Nowadays there are a lot of optical interferometric tests, but there is no doubt the most used, among the lateral shear interferometry is the Ronchi test. In this work we implement the Bi-Ronchi test by generating a square Ronchi ruling onto a LCD. Phase shifting interferometry and a matrix method were used to recover the wavefront aberration. Plots of the surface under test and wavefront abberations are also shown.
