Laser diffraction analysis or laser diffraction spectroscopy is a scientific technique which utilizes properties of the diffraction patterns of a laser beam passed through a substance, to measure the size of its particles. Laser diffraction analysis is based on the theory of Fraunhofer diffraction, which states that the intensity of light scattered by a particle is directly proportional to the size of the particle.
