Abstract

Optical coherence tomography (OCT) is an emerging cross-sectional imaging technology. Compared with other imaging methods, OCT has its unique features including ultrahigh resolution, non-invasion, non-touch and easily combined with fiber. OCT is sensitive enough to get cross-sectional image of bio-tissue(transparent and turbid) . In this paper, the principle of OCT is presented and the crucial parameters which influence the quality of image are discussed in theory. Based on the analysis of different method and medical endoscopic system's feature, a design which combines the spectral OCT(SOCT) technique and endoscopy is put forward. At the meantime, a novel OCT probe which uses advanced min-motor to drive reflecting prism is designed according to alimentary tract endoscopy's feature. Interference part, spectral receiving part, data acquisition and disposal part are built up. An experiment which uses multi-layered cover-glass as sample is done. The result verifies the feasibility of endoscopic optical coherence tomography system with rotating scan.
