High Speed Spectral Optical Coherence Tomography for Imaging Biological Tissue In Vivo

Abstract:

A high speed spectral optical coherence tomography (SOCT) system was demonstrated. An achievable scanning speed of 92k line/sec has been reached and it can acquire 3-dimensional data sets in ~3 second. The axial resolution of ~13μm and lateral resolution of ~16μm have been realized. The system is capable of a theoretical depth measurement 3.2mm in air. We also measured the sensitivity performance corresponding to difference depth and it demonstrated that our system can differentiate signal form noise at 3mm pathlength difference. Using the system, human palm skin was measured in vivo.
