Abstract:A digital in-line holographic recording and reconstruction method is used in the particle image for the diameter measurement. In digital holography, image reconstruction is carried out numerically on a computer by using observed hologram patterns and some quantitative information can be derived from the reconstructed images which are properly segmented by using threshold selection method(MEM). The particle boundary is determined by Laplacian of Gauss operator. The diameter of particles can be obtained by calculating the size of the particle. The experiments indicate a rate of errors of less than 8%.
