摘要: 光学弱相干层析成像技术结合了共焦、弱相干、光外差及扫描层析成像等技术的优点,可实现无损伤、在体检测,具有较高的探测灵敏度和分辨率,可望在生物组织活检中获得广泛应用。本文在讨论OCT基本原理的基础上,介绍了OCT系统的若干应用,如龋齿、体内器官粘膜的成像检测和对血管结构与血流动力学的成像检测等。

Abstract: Optical conference tomography combines advantages of confocal, low coherence, optical heterodyne detection and scanning tomography and realizes non-invasive and in vivo measurement. Since OCT has relatively high spatial resolution and sensitivity, widespread applications are possible for biopsy. In this paper, we will give an introduction to optical coherence tomography (OCT) and then discuss several applications, such as imaging of a canes lesion in the fissure, mucous membrane of internal organs, vessel structure and blood flow dynamics.
