Optlcal Coherence Tomography System Research

The optical coherence tomography is the advancing edge and hot field of the burgeoning subject branch, Biomedical Photonics which crosses the subjects of Optics, Electronics, and Computer Science, etc. It is also the landmark to achieve the noninvasive and high resolution biomedical tomography.In order to overcome the difficulties of OCT and meet the requirements of native development of OCT, the theory, design, fabrication, alignment and data process of OCT were studied to finally improve the performance of OCT and generate our own intellectual property rights.The reference beam of the OCT system which has axial scanning function, is the most important part that the OCT system can chromatographic analysis fast and precisely, this testing plan choose the optical fiber OCT system which based on double-pass rapid scanning optical delay line (RSOD) for this experimental system..Finally, we designed and fabricated an OCT system.Then we measured the axial resolution and experimented on tomographic image for some samples.The results show that the axialresolution of our fabricated OCT has reached 18μm ,which is advanced in our country.
