1. An optical apparatus for identifying individual multiparametric properties of particles or bodies moving in a continuous flow, said apparatus comprising:

  • an open-ended, non divergent quadric reflector having a focal point,a transparent, continuous capillary tube passing through said focal point of said reflector and providing for the movement, individually, of particles in suspension in a fluid medium,radiating means capable of directing a beam of radiation normal to the direction of particle movement in said capillary tube through said focal point, said beam of radiation upon striking said particle producing different rays,a mask obstructing a portion of said diffracted rays scattered by a particle intersecting the incident beam of the radiating means at the reflector focus and not striking the reflector,a detecting means for receiving the various reflected scattered rays for producing a signal thereof,and means for processing and using said signals supplied by said detecting means.
