Introduction

The Optical Coherence Tomography (OCT) is an optical measurement technique used for investigation of wide range of scattering or semitransparent materials. The OCT enables surface and subsurface examination of different types of materials to be performed in non-contact and non-destructive way. With the aid of OCT one can visualize the depth structure of investigated materials, measure its thickness and also detect some defects and inhomogeneities with measurement resolution of few µm, high sensitivity and dynamic range. Nowadays, the advantages of OCT make it applied in medical diagnosis especially in ophthalmology, dermatology, stomatology and endoscopy as well, as in industry and science. Beyond medical applications the OCT is used for material characterization, surface and subsurface defect localization, strain fields mapping in polymers, ceramic materials examination, as well as art conservation. The high application potential makes the OCT an interesting tool for scientists and researches from many fields of interests.
