Paper Abstract

Dispersion of optical elements and sample in optical coherence tomography (OCT) system introduce a wavelength dependent phase distortion to the light beam propagating in OCT system. This causes blurring of the image in high resolution OCT using broadband light sources. Also decreased resolution with the depth of a sample is observed. To avoid this, the overall dispersion of the system can be compensated using a dispersive material in the reference arm of a system. Unfortunately, the dispersion is changed in the system with the probing depth. Overcome to this problem is numerical dispersion compensation technique. Calculations can be made after the measurements have been taken to provide depth dependent compensation. Various techniques and their possibilities are presented.
