Abstract
A device for observation and analysis of a cross-sectional portion of a stream of material, which may be either a particle or a fluid stream, includes a laser light source for generating a beam of light. A focusing lens is disposed in an optical path between the laser source and the stream and a plano-cylindrical lens of a selected focal length is disposed in the optical path between the focusing lens and the stream. The focusing lens and the plano-cylindrical lens convert the beam of light from the laser light source to a plane of light which may be projected through the stream to illuminate a selected cross-section of the stream for observation and analysis thereof.
