Imaging below fingertip surface might be a useful alternative to the traditional fingerprint sensing since the internal finger features are more reliable than the external ones. One of the most promising subsurface imaging technique is optical coherence tomography (OCT), which, however, has to acquire 3-D data even when a single en face image is required. This makes OCT inherently slow for en face imaging and produce unnecessary large data sets. Here we demonstrate that full-field optical coherence tomography (FF-OCT) can be used to produce en face images of sweat pores and internal fingerprints, which can be used for the identification purposes.
由于手指内部特征比外部特征更可靠，指尖表面以下的成像可能是传统指纹传感的一种有用替代方法。最有前途的表面下成像技术之一是光学相干断层扫描（OCT），然而，即使需要单个正面图像时，它也必须获取三维数据。这使得OCT在进行正面成像时本质上速度较慢，并会产生不必要的大量数据集。在此我们证明，全场光学相干断层扫描（FF-OCT）可用于生成汗孔和内部指纹的正面图像，这些图像可用于识别目的。
