Abstract

Optical coherence tomography (OCT) is a non- invasive technique where a near-infrared laser beam penetrates a sample and through the analysis of its scattered light information about the internal structure of the sample is calculated. Although OCT is mainly used in medicine its application to areas of enginery has been increased recently. Important features of recent OCT systems allow us to determine accurately volumetric structure not only slices. In this works we report such volumetric analysis applied to the study of scratches and damages in optical elements in order to quantify not only the scratch sizes but also its depths. This study is compared with an Schlieren technique. Experimental results are presented. The finding reveals clearly the faults locations which may be an attractive results for the optical work shop and the application of norms.
