Abstract

We present a new method of numerical dispersion compensation in spectral domain optical coherence tomography based on the fractional Fourier transform. The dispersion induced by a 26 mm length water cell was compensated for a spectral bandwidth of 110 nm, allowing the theoretical axial resolution in air of 3.6 μm to be recovered from the dispersion degraded point spread function of 49 μm.
