摘要
基于迈克尔逊干涉原理的光学相干层析成像技术 (OCT)是近年来发展起来的一种新型的成像技术 ,其显著特点是具有高分辨率、非侵入性。传统的 OCT系统通常采用点扫描方式获取二维图像 ,其速度较慢 ,限制了系统的实时探测。介绍了一种高速的光学层析成像系统 ,即以线扫描方式代替点扫描 ,这种方法可将扫描速度提高两个数量级 ,能实现在体实时探测 。
Optical coherence tomography (OCT) based on the theory of Michelson inteferometer is a novel imaging technique with high resolution and nonivasive.The traditional OCT system produces a two dimensional image through point scanning whose scanning speed is slow,and it limits the real time measurement of the system.This paper introduces a new imaging technique of high speed imaging OCT system,using line scanning method instead of point scanning method.The new method can increase the scanning speed and realize real time measurement,which is the base of high speed scan imaging.
