Accurate wavelength calibration is necessary to maximize imaging resolution and sensitivity in the spectral domain optical coherence tomography (SD-OCT) systems, which is the process of determining the wavelength distribution on a line-scan CCD. We present a novel method of calibrating the wavelength distribution of a spectrometer based on the broadband source spectral in SD-OCT system. This method uses the extreme points of the source spectrum and the corresponding CCD pixel points to establish a functional map. Therefore, additional calibration source with narrow spectral lines is not required. Third-order polynomial fitting function is obtained to fit the relationship between the CCD pixel number and the characteristic wavelength. As a comparison, this paper firstly tests the mercury-based argon lamp calibration method, analyzes its performance, and then tests the source-based calibration method. After comparing the curve parameters, we verify that the performance of the source-based spectral calibration method is as good as the mercury argon lamp calibration method. The feasibility and accuracy of the new method are verified by fitting results, sensitivity map and imaging. With the new calibration method, the sensitivity of the system roll-off of 2.163 dB / mm and high quality two-dimensional (2D) imaging of rubber tube is realized. This method is much simpler and reduces the cost because no additional calibration source is required.
