Title:
METHOD AND DEVICE FOR MEASURING POSITION, PARTICLE SIZE AND VELOCITY OF FINE DROPLET, BUBBLE AND PARTICLE
Document Type and Number:
WIPO Patent Application WO/2007/138818
Kind Code:
A1
Abstract:
A measuring method capable of measuring the position, the particle size and the 3-component velocity of a particle concurrently and accurately for all quantities. Especially, a measuring method capable of measuring a position, velocity components and a particle size in a direction perpendicular to a laser sheet concurrently and accurately. A particle size/3-D position measuring method comprises the steps of using, in a laser interference imaging method, a plurality of imaging optical systems for performing out-of-focus photographing, locating these at different looking-angle positions and photographing them, specifying identical particles out of a plurality of particle images in images obtained from respective imaging optical systems based on a plurality of pieces of particle size information on identical particles or an interference fringe signal including particle size information that are obtained from respective imaging optical systems, measuring their particle sizes, and measuring the 3-D positions of individual particles along with the above particle sizes based on a 3-D vision principle.
