A Review on Development of a High Resolution Imaging System at 635 nm and 840 nm

Abstract: This Optical Coherence Tomography (OCT) technique is a non-invasive technology used in medical as well as in non-medical applications. It is used to produce high resolution images. It provides the cross-sectional images of an sample in X & Y direction. It provides the depth as in millimeter range with the resolution in micrometer range. A broadband source of light is used so as to get the more bandwidth. The light beam is get splitted by the sample arm & reference arm respectively. An optical detector is used to detect the back-scattered light from the sample & reference arm. The matlab algorithm is used to process the signal. By moving the sample in X & Y direction, we can get the appropriate 2D & 3D images.
