| 摘 要： | 改进和完善宽场光学相干断层成像技术(WFOCT)的主要方法是从光源、系统光路等方面进行改进.研究WFOCT系统的成像状态和环境状态对系统的横向分辨率的影响,借助ZEMAX光学设计软件模拟该系统的干涉效果,在实验中采用八步移相法来解析样品的二维图像信息,将解析出来的样品图像赋值到图像变量中进行存储显示.实验与模拟结果表明:模拟仿真获得的干涉信号含有对比度和平行度很高的干涉条纹,证明了利用ZEMAX软件模拟仿真干涉系统的可行性.

| Abstract: | The major method to improve the wide-field optical coherence tomography (WFOCT) is to meliorate the light source and beam path of optical systems. The effect of the imaging state and environment of a wide-field optical coherence tomograph on its transverse resolution was investigated. The interference effects of the system were simulated by the aid of ZEMAX software. The 2-D image information of the sample was analyzed with the eight-step phase-shifting technique in the experiment. The simulation results show that the interference fringe with better contrast and high parallelism can be acquired by simulation, and verify the feasibility of simulating the interference system by ZEMAX software. |
