Research on Particle Size Distribution Technology and SystemBased on MIE Theory

Particle size measurement is widely used in powder engineering, measurement results affect the quality of powder products directly. After in-depth study of MIE scattering theory, proposed a design of particle size measurement system based on improved inversion algorithm. By use of laser, Fourier lens, photoelectric sensor to collect electrical signals containing particles information, and through conditioning circuit for signals processing, using improved inversion algorithm analyze and calculate the value of particle size distribution. Experimental results verified that the proposed design can achieve particle size measurement accurately and efficiently.
