Verfahren zur Unterdrueckung der Mehrfachstreuung bei Untersuchungen an trueben Medien mittels Kreuzkorrelationstechnik

WO 200295368 A UPAB: 20030121 NOVELTY - For adjustment of the method two laser beams use used to illuminate an examination volume in a container. Scattered light from the laser beams are detected using detection optics. The vectors of the scatter geometry are arranged so that they are tilted relative to a plane running through their intersection point and so that the laser beams (k1, k2) are unsymmetrically arranged relative to a plane running through the intersection point. Thus at least parts of the same light spots are recorded by both detection lenses. USE - Suppression of multiple scattering in measurements in turbid media by use of a cross-correlation technique. ADVANTAGE - The inventive cross-correlation method ensures that multiple scattering is suppressed and measurements are more accurate
