摘要

The atomic force microscope is a very useful tool for use in biology and in nano-technology, since it can be used to measure a variety of objects such as cells and nano-particles in a variety of different environments. However, the images produced by the AFM are distorted and do not accurately represent the true shape of the measured cells or particles, even though many researchers do not take this fact into account. In this paper we determine the impulse response of AFM using experimental results gathered from measuring the cylindrical sample via AFM. Once the AFM impulse response is estimated, the Lucy- Richardson algorithm is used to calculate the deconvolution between the resultant AFM impulse response and the blurred AFM image. This produces a more accurate AFM image. Also in this paper, we compare raw experimental AFM images with the Restored AFM images quantitively and the proposed algorithm is shown to provide superior performance.
