　　目的为更加准确地研究人眼调节时整个眼前节的形态变化特点，开发一种新的基于光学相干层析技术的眼调节成像与测量系统。方法利用弱相干光干涉原理，模块化双通道双焦点设计，以两个迈克尔逊干涉仪为核心研制该SD-OCT系统。结果该系统可同时获取整个眼前节（角膜，前房，虹膜和晶体前、后表面）的图像，并对由调节引起的动态变化进行实时检测分析。结论初步临床上试验结果表明该系统是一种重复性较好的全眼参数的测量仪器，它具有操作方便、非接触性及实时获得高分辨率眼前节图像的优点。

Objective To develop a spectral-domain optical coherence tomography(SD-OCT)system , for precisely imaging the accommodation of the anterior segment of the human eye. Methods Design the SD-OCT system based on two Michelson interferometer by using the basic principal of weak coherent light interference and modular design of dual channel dual focus. Results The system can provide simultaneous cross-sectional imaging of al the surfaces of the anterior segment of the eye including the cornea, anterior chamber, anterior and posterior surfaces of the crystal ine lens. Thus, the dynamic change of modification of the curvatures can be calculated in real time. Conclusions The system was successful y tested in imaging accommodation, with high resolution and non contact. The preliminary results demonstrated the feasibility of this novel approach to measure the eye parameters.
