In the scan setting of remote sensing ,the 45 °rotating scanning mirror is the most abroad and foreground in appling. It has more excellence than the other scanning settings. The image rotating produced in the process of 45°rotating scanning restricts the use of multi-pixel parallel scanning. If appling this scanning mode must settle the problem of the image rotating.In the all methods, the merit of the software blue print is stand out. It is important to study the influence of the detector number of wave band and the position of the wave bands on the result and analysis the aberrance degree of scanning image aroused by the changement of the parameter.In this paper , on the basis of the vector theory of optical refraction a scanning trace of 45 ° multi-parallel scanning mirror was analysed , and the corresponding formulas are given.Furthermore , the aberrance to remote sensing imagination in existence of 45 ° multi-parallel scanning mirror and the influence of the detector number of wave band and the position of the wave bands are analysed. The result is that if to minish the degree of image aberrance the pixels of the wave bands must in the position most near to the main ray axes. The image-rotating problem can be settled by the means of software emendation and the actualizing blue print is presented.The scheme of imagination rotating aberrance through software emendation was primarily experimented. As a result, the effect of software was better and thus it proved the scheme feasible. In the bases of scanning formula, the wavelength scope is nicety and the effect of image composition is all right. In the last, we summarized our research and put up with shortages of this article.
