The Determination of Cyclonic Particle Field with Off-line Holography

Introduced the distribution of particle field in industrial cyclonic dust-collector with off-line holography. A holographic construction system and the appropriate reconstruction system will be disscussed regarding their characteristics and performance (i.e. system resolution, system aberration and correction of aberrations, and maximal total text volume). It will be shown that by using the method described, the particle with 5μm can be captured. It is very profitable for the improvement of cyclonic dust-collector in industry.
