Optical coherence tomographic images of human dentin and enamel are obtained by use of polarization-sensitive optical coherence tomography. A birefringence effect in enamel (lambda = 856 nm) and light propagation along dentinal tubules are observed. The group index of refraction for both dentin and enamel was measured at 1.50 +/- 0.02 and 1.62 +/- 0.02, respectively.
利用偏振敏感光学相干断层扫描技术获取人牙本质和牙釉质的光学相干断层扫描图像。观察到牙釉质中的双折射效应（波长λ = 856 nm）以及光沿牙本质小管的传播。牙本质和牙釉质的群折射率分别测量为1.50±0.02和1.62±0.02。
