Abstract: This Optical Coherence Tomography (OCT) is a non-invasive technology which is used in medical and non-medical applications to produce high-resolution images. It provides the cross-sectional images of an object in real time. It is based on low coherence inter ferometry to get the depth resolved information of the sample. The depth of imaging is in millimeter range with the resolution in the micrometer range. The broadband source of light is split by the beam splitter and directed to the sample arm and reference arm respectively as is the case in Michelson’s interferometer. The CCD photo-detector used in the NIR spectrometer detects the interference produced by the backscattered light. The Matlab script is used to convert this backscattered data into an image pertaining to one axial scan (A-scan). Final 2D/3D image is constructed by performing A-scans at various points of the sample in the XY plane.
