Abstract

We propose a simple, numerical procedure for dispersion mapping of an object, which can be easily used for every OCT data set acquired from a Fourier domain system employing light source of sufficiently broad spectral bandwidth. The mapped value is Group Velocity Dispersion and its determination is based on the estimation of the difference in material’s thickness calculated from two images obtained for different spectral ranges. Instead of using two separate light sources to achieve that, we propose to apply a filter-based, numerical procedure that synthesizes two spectra centered around different wavelengths from one sufficiently broadband spectrum.
