ABSTRACT:
Method and apparatus for improved optical discrimination in a total particle population of particles having a significant light absorption characteristic and particles having a significant light scattering characteristic. There is provided in such a method a combination of steps including, directing a beam of light from a source to transversely illuminate at an optical interaction station particles passed one by one through such station, partially obstructing the beam beyond the station for passage of scattered and unscattered portions of the beam, when a particle is in said beam and detecting one of said beam portions.
