Abstract
A broad band radiant energy beam is passed through a sample region that contains particulate matter. The emergent beam is applied to a plurality of photodetectors, each one of which is made responsive to a different narrow band portion of the beam. The thus obtained electrical signals are applied to a computer which is programmed to process the electrical signals and read out either the size distribution parameters or the mass concentration of the particles in the beam.
