The AFM image will be distorted due to the tip-broadening effect. It may be mathematically represented as the effect of the tip’s<BR>convolution on the real image. As a result, the true geometry of the sample surface can not be obtained. If the tip shape could be<BR>known accurately, such distortion can be eliminated with the adoption of disconvolution operation. It is of practical significance in<BR>the accurate reconstruction of the AFM image. Among the current tip modeling algorithms, the bli
