Paper Abstract

Deflectometry is an optical metrological technique to determine the shape of test surfaces. This technique is based on the measure of the deviation that the light suffers when impinges the test surface and is reflected. The information of the surface slopes is contained in the reflection angle. Then, the integration of the slopes is necessary to obtain the final profile of the surfaces. In this work, we present a brief review of two dimensional integration methods and we propose a new two dimensional integration method. A comparison of the integration methods is presented in term of the mean quadratic error between the original profile and the profile obtained by integration.
