光学相干层析成像（OCT）是一种基于低相干干涉术的高分辨率成像技术。在生物组织中进行OCT成像时，几乎不可避免地会出现色散。我们量化了基于光栅的光延迟线可能引起的群速度色散及其对oct轴向点扩展函数的贡献。对基于光栅的光延迟线色散进行建模的实际原因之一是，在最大补偿下，它可以深入了解组织的色散特性。
Optical coherence tomography (OCT) is a high-resolution imaging technology based on low-coherence interferometry. When OCT imaging is performed in biological tissue, dispersion almost inevitably occurs. We quantify the group-velocity dispersion that a grating-based optical delay line may induce and its contribution to the axial point-spread function of OCT. Among the practical reasons for modeling the dispersion in grating-based optical delay line is that, at maximum compensation, it can provide insight into the dispersive properties of tissues.
