Paper Abstract

A two- and three- dimensional swept source optical coherence tomography (SS-OCT) system which uses a ready-to-ship scanning light source is demonstrated. The light source has the center wavelength of 1.31 μm, the -3 dB wavelength range of 110 nm, the scanning rate of 20 KHz and high linearity of frequency scanning. A simple calibration method using a fringe analysis technique for spectral rescaling is presented. This SS-OCT is capable of realtime display of two-dimensional OCT, and can take three-dimensional OCT with the measurement time of 2 s. In vivo human anterior eye segments are investigated both two- and three- dimensionally. The system sensitivity is experimentally determined as 113 dB.
