国内利用超连续谱作为OCT光源的研究较少,起步也较晚。2009年,天津大学精密仪器与光电工程学院郭以平等人利用亚皮秒脉冲光源抽运由不同特性光纤级联而成的混合非线性光纤来产生超连续谱,得到1300nm处3dB谱宽为140.6nm的宽带光谱。用此宽带光源作为光学相干层析系统光源,可以在生物体探测窗口约1300nm处达到小于4.1μm的纵向分辨率[11]。
综述:上述详实的文献充分表明了OCT技术在生物医学应用中的重要性,并且从各个方面对OCT技术的发展与应用做了分析研究。薛玲玲、王新宇等人最先概述了OCT在生物医学上的应用。刘伟、姜宇等研究了OCT的工作原理。钟会清、王淑霞等人研究了OCT在特定领域的应用。本文将在结合前人研究的基础上,根据目前OCT的发展与应用情况,对OCT的发展、原理及生物医学上的应用进行研究。
