Abstract

The optical method of simultaneous measurements of velocity and size of moving particles are described. The method based on numerical processing of the impulses of the photo receiver registering intensity of radiation diffracted on moving particles. Usage of photodetectors with the special shape of photosensitive areas and special computer programs allow simultaneously and separately to measure speeds and sizes of drops, including "large" with radius R>1 mm and more. The examples of implementation of the method are adduced.
