Paper Abstract

A method for dispersion compensation in optical coherence tomography (OCT) by a double-grating based rapid scanning optical delay line (RSOD) is put forward. The added grating introducing an independent variable of the distance between gratings, along with the adjustable distance between grating and Fourier transform lens in a conventional RSOD can be used to compensate the group velocity dispersion (GVD) and the third order dispersion (TOD) of OCT system simultaneously. Theoretical development of the dispersion characteristics as well as the dispersion management scheme is given. Example of dispersion compensation in a typical OCT system is provided.
