We present the design and procedures for implementing a parallel optical coherence tomography (POCT) imaging system that can be adapted to an endoscopic format. The POCT system consists of a single mode fiber (SMF) array with multiple reduced diameter (15 microm) SMFs in the sample arm with 15 microm center spacing between fibers. The size of the array determines the size of the transverse imaging field. Electronic scanning eliminates the need for mechanically scanning in the lateral direction. Experimental image data obtained with this system show the capability for parallel axial scan acquisition with lateral resolution comparable to mechanically scanned optical coherence tomography systems.
我们介绍了一种可适配于内窥镜形式的并行光学相干断层扫描(POCT)成像系统的设计与实施步骤。该POCT系统在样品臂中包含一个单模光纤(SMF)阵列,其中有多根直径减小(15微米)的SMF,光纤之间的中心间距为15微米。阵列的尺寸决定了横向成像视野的大小。电子扫描消除了在横向方向进行机械扫描的需求。使用该系统获得的实验图像数据显示了并行轴向扫描采集的能力,其横向分辨率与机械扫描光学相干断层扫描系统相当。
