The Study of the Action between Particles Using On-Line Holographic Method in High-Intensity Particle Field

The action between two particles in particle field is studied in this paper with the aid of the disc-particle model and the Fresnel formula.It is shown from the quantitative computation that the main factors of affecting the particle field character, come from particles size and their distribution. We found that information of the large particle may be recorded easier than the small particles, and the particle in small size may be lost. For this reason we difine this phenomenon as "large particle effect". In other hand, the scatter light of particle makes their optical information engendering distortion. The distortion level depends on the far-field number.These conclusions are of great importance when we recognize every particles using the image procedure system to analyzing the static distribution of particle field.
