| Abstract: | A method for measuring diameters of tiny particles in water by laser, CCD image sensor and processing of image signal is presented. The measuring principle, measuring system and experiment results are introduced .The experiment indicates that there is an obvious regulation between the image diameters of particles and the real diameters of particles . The method is suitable for testing diameters of solids in rivers and diameters of gas bubbles in water. |
