Spectral Optical Coherence Tomography

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.

Focusing Lens

A high-speed, high-resolution swept-source optical coherence tomography (SS-OCT) is presented for focusing lens imaging and a k-domain uniform algorithm is adopted to find the wave number phase equalization. The radius of curvature of the laser focusing lens was obtained using a curve-fitting algorithm. The experimental results demonstrate that the measuring accuracy of the proposed SS-OCT system is higher than the laser confocal microscope. The SS-OCT system has great potential for surface topography measurement and defect inspection of the focusing lens.
