Abstract
A particle analyzer system which operates on-line, real-time and is adaptable to use in process control systems wherein the analysis provides a basis for control of the process. Images of particles are focused onto an array of light sensitive electronic elements. The resulting light pattern is translated into digital data which is retrievably stored in a memory. Analysis of the data by digital logic yields information as to particle counts, size, shape and other physical characteristics. Interim storage in the light sensitive array itself is provided which allows data accumulation using short duration stroboscopic illumination.
