摘要：The present invention provides method of particle size and concentrationmeasurement that comprises the steps of: providing a focused, synthesized, non-Gaussian laser beam, causing the beam to interact with the particles, measuring theinteraction signal and the number of interactions per unit time of the beam with theparticles, and using algorithms to map the interaction signals to the particle size and thenumber of interactions per unit time to the concentration. The particles are fluid borne,airborne, or on a surface and have a size ranging from sub-micron to thousands ofmicrons. In a preferred embodiment of the invention, the focused, synthesized, non-Gaussian laser beam is a dark beam. The non-Gaussian beam can be generated byemploying a mask over a Gaussian laser beam or by directly modifying the laser cavity orby combining the beams from several lasers. The measurements can be made using theduration of interaction with a scanning beam, including dark field. The invention furtherprovides a system for particle size and concentration measurement.
