Abstract:
I An Optical Coherence Tomography(OCT) for tissue imaging with high-resolution, based on 51 serial single chip microcomputer has been developed. The operating principle, hardware construction and soft design of this system are expounded in detail in this paper. The self-made samples and bio-samples were measured by this OCT system. The results show that this OCT system has the advantages of high resolution, high sensitivity, intellectualization and noninvasiveness.
Keywords:OCT   low coherence   optical heterodyne detection   single chip microcomputer
