Application of graphically oriented programming to imaging of structure deterioration of historic glass by Optical Coherence Tomography

摘要

Optical Coherence Tomography (OCT) is an interferometric method utilising light of low temporal coherence for non-invasive structural imaging of objects weakly absorbing and scattering light. In this contribution, using various examples of images of objects made of glass affected by the atmospheric corrosion and/or by crizzling, we demonstrate a software developed in our laboratory specifically for 3D OCT imaging of samples with a fine structure. For this task we employed the OpenGL platform (Open Graphics Library), an Application Programming Interface (API) for writing applications dedicated to interactive 3D computer graphics. In our application we have utilized texture rendering with a modulation of transparency and a colour as a function of elevation.
