Abstract
We demonstrate dynamic spectral shaping in an optical coherence tomography (OCT) system with multiple scans of segmented spectral bands and software signal processing. With an effective spectral full-width at half-maximum (FWHM) of 45 nm, centered at 950 nm, we compress the interference fringe FWHM from 31 microns down to 7 microns, which is smaller than the theoretical limit of 8.9 microns if a Gaussian spectral shape is assumed, through the combined effect of dispersion compensation and spectral shaping.
