Abstract

In biomedical imaging high speed axial scanning is very important for obtaining the cross-sectional images of tissue microstructures. For this purpose our optical coherence tomography (OCT) system incorporated a scanning optical delay line (RSOD) that uses Fourier-transform pulse shaping technique. In this technique axial scanning in the time domain is implemented by a linear phase ramp in the frequency domain. By combining the axial scanning (Z-axis) in the reference arm and lateral scanning (X-axis) in the sample arm using a lateral scanning galvanometer, the system could image samples with a size of 400×800 pixels (Z-X image) at the speed of 6 frames per second. Some imaging results are presented in this paper.
