Abstract
In the particles' size optical measurements, the distribution of particles' size is often caculated upon the diffraction image, so the quality of the image is very important. But in the real case, information data of the image both in high bright area and consulted area are often lost because of the overflowing of zero grade diffraction stripe and submersing of high grade diffraction stripe, but for the disfigurement of optical element, speckle and system accepting-error. In this paper, a new method of double filter data processing is put out, that is, the image is first divided into some net-section, the integral-average of scattering energy in this section is chosen as a rebuilt data, and second, non-linearity alternated processing is put out to reduce the trouble affecting and with in the probability idea the probability brightest dot data is set as 1, the backdrop probability data as least at the proejcted section. At last, a high qualty image is rebuit in 3D with this two filter processing after processing by a computer.
