An approach,known as Edge Tracking Method,has been developed in particular,which searches out the outer edge and the central spot edge of the coherent image of a particle.The processing procedure of the digital images and its program have been worked out in detail.Finally,the outer size and the central size a particle image are determined by means of the presented technique,then the particle size and its position are calculated by means of the Three-Dimensional Judgement Technique.The results obtained are reasonable.
