我们使用两个反向级联的线性啁啾光纤布拉格光栅和全光纤元件实现了全光纤延迟线。本文从理论上讨论了基于全光纤的可变延迟线技术的特点，并进行了实验验证。利用实现的全光纤延迟线获得了生物医学样品的无创截面图像和透明玻璃板，其轴向分辨率为100 μ m，动态范围为50dB，验证了成像性能，并证明了延迟线用于光学相干断层成像的可行性。
We have implemented an all-fiber optical delay line using two linearly chirped fiber Bragg gratings cascaded in reverse order and all-fiber optics components. The features of the proposed all-fiber based technique for variable delay line are discussed theoretically and demonstrated experimentally. The non-invasive cross-sectional images of biomedical samples as well as a transparent glass plate obtained with implemented all-fiber delay line having the axial resolution of 100 mum and the dynamic range of 50dB are presented to validates the imaging performance and demonstrate the feasibility of the delay line for optical coherence tomography.
