Laser-optical arrangement for measuring the degree of dispersion in flowing systems

摘要

In a laser-optical arrangement (1, 5) for generating scattered-light, obscuration or reflection signals from individual particles flowing in a flow-type cell (6), the signals are recorded by a photodetector (2) via suitable imaging optics (3) as a voltage/current variation with time and an rms value measuring system (4) rates the degree of dispersion of the flowing system. <IMAGE>
