Abstract

A new optical correlation method is developed for measuring the scattering-particle size distribution function. The method is based on the transformation of the transverse coherence function of the scattered field that forms the scattering-particle images. A device for measuring the scattering-particle size distribution function is proposed that has a response time of about 10 s and can be applied to measure particles with sizes in the range of 3 to 500 μm to within 10%.
