Laser diffraction analysis
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.[1]
The laser is passed through the substance being examined, and the diffracted light focused onto a detector which measures the angular distribution of the intensity of the scattered light.[2]
