| Abstract: | Because of multiple pass of the optical rays in the optical coherence tomography (OCT) system based on time-domain structure, it would be difficult to adjust the system set in accordance with the principle of optical reversible. From theoretical analysis and experimental research, a rapid method which can shorten the operating time of the system adjusting is summarized. The adjusting techniques for the axial Fourier rapid scanning optical delay line and lateral scanning system are described step by step in detail, the approach for rapidly matching of optical path lengths is proposed and implemented. Experiments using the tomography system constructed were conducted, the OCT images were reconstructed through the scanning to the biological sample after the depth calibration of the axial scanning. |
