| Abstract: | In this paper, the fundamental principle of optical coherence tomography is presented. Based on embedded microprocessorS3C2443 in ARM9 series and widely-used real-time multi-task operating system WINCE, a design for spectral OCT endoscopic imaging system in order to detect pathological changes on human gastrointestinal tract is brought forward. The process of developing system is particularly introduced in both aspects of hardware and software. The system architecture and programme flow chart are proposed. Besides, experiments with three-layered cover-glass used as sample for rotating imaging are successfully finished, which effectively show that the spectral OCT system will be competent for imaging. |
