In order to execute the measuring method of the particle quality which penetrates into the body, the quality measuring method of the flow material, the sound particle velocity measuring method, and measuring method of the flow material the device which is prepared

摘要

Complicated optical constitution it does not need, it is more accurate, it gathers the statistics of the analysis which is suited for the purpose of especially droplet-size distribution measurement to possible. It includes below, the body (B) measuring method of quality of the particle which penetrates inside. As diffused radiation (155) occurred with the dispersion interaction of the light ray and the particle, specified width D and the time coherent light ray which possesses specified wave length (152) it is due to the illumination of the body which is accompanied, execution of consecutive instantaneous collection, and, many value of the entire radiant intensity which comes, from the body with the many point simultaneously (155, 156, 155 ' and 156 ') as for detection and the point, substantially the particle is dispersion possible, the diffused radiation which comes from all directions (155 and 155 ') it seems that it can receive substantiallyIt is the point which is distance z from the body, and, each point receives, diffused radiation of the many particle (155 and 155 ') and, quality of the particle, in the kind of method of measuring, processing of consecutive collection (100).
