Paper Abstract

Depth dependent broadening of the axial point spread function due to dispersion in the imaged media, and algorithms for postprocess correction have been previously described for both time domain and frequency domain optical coherence tomography. Homogeneous media dispersion artifacts disappear when frequency domain samples are uniformly spaced in circular wavenumber, as opposed to uniform sampling in optical frequency. In this paper, we explicate the source of this point spread broadening and simulate its magnitude in aqueous media. We conclude with a suggestion for interferometric k-triggering which accounts for dispersion in the media.
