光学相干层析成像（OCT）的轴向分辨率取决于光源的相干长度。我们展示了第一次高分辨率OCT的生物组织使用卤素灯作为光源的低相干干涉仪。尽管用于样品照明的相干光功率小至100 nW，但成功地对洋葱和猪皮进行了分辨率为3.5 μm的高分辨率OCT成像。
The axial resolution of optical coherence tomography (OCT) is determined by the coherence length of the light source. We demonstrate for the first time high-resolution OCT of biological tissue using a halogen lamp as the light source for a low coherence interferometer. High-resolution OCT imaging with 3.5 μm resolution was performed successfully for onion and porcine skin, although the coherence light power for illumination of a sample is as small as 100 nW.
