Abstract— The resolution of optical coherence tomography is In this paper, we present a numerical method for correcting
degraded the dispersion of samples, as well as the dispersion dispersion related resolution loss in OCT system. Our
introduced by optical structure. Water is taken as sample, and means techniques for dispersion matching of the two interferometer

according to optical characteristics of water. The dispersion effect in a enhancement of sharpness of a cover glass under water. Also,
an image of muscle tissue of mouse is also corrected. In experience, the dispersion of a rapid scanning optical delay line (RSODL)
