Beschreibung
Zusammenfassung:	In a laser-optical arrangement for producing signals by light scattering, obscuration or reflection, from flowing particles and/or groups of particles, which are recorded, as time-dependent voltage/current fluctuations, by means of a photodetector (9) via appropriate imaging optics (7,8,18), assignment to the degree of dispersion of the flowing system is based on a subsequent measurement (10) of the root-mean-square value, and, according to the invention, the sample stream (1) is separated from a transmitter (6,7,18) and a receiver (8,9,10) by an enveloping stream (4), and the transmitter side consists of an individual light-transmitting fiber (7) provided with a means for parallel or focused emergence of a light bundle having a diameter of the order of magnitude of the particles and/or groups of particles.
