Wavelength calibration coefficients were calculated through regression analysis after several ordinal numbers of CCD's pixels corresponding to Mercury-Argon Lamp's spectral lines were measured. The residuals of certain spectral lines were computed using the coefficients measured and the ones from factory, the degree of fitting for regression equation was estimated using the new coefficients. The final results validated the wavelength calibration model.

One kind of such information is the geometry about an object in the space. The algorithm to extract such a kind of information usually includes an important procedure called "camera calibration." The purpose of camera calibration is to construct the relationship between the image plane of the camera and the coordinates system of the object space. The relationship is usually represented by a "mathematical function."
