Paper Abstract

We present the methodology for the surface measurement of small testing objects with maximum depth variation of 3mm, using a polarimetric approach. The experimental setup is based on the function of a Differential Interference Contrast microscope, which works as a shearing interferometer. As it is expected, when it comes to an application for non-microscopic samples, certain modifications should be considered on the development of the measurement system. This work focuses on such details that lead to the profiling of a testing object of known dimensions. An algorithm that computes height distribution based on the polarimetric data is implemented and the resulting surface profile is analyzed. Finally, our conclusions about the requirements for an improvement of the presented measurement setup are listed.
