摘要

A method for the suppression of the multiple scattering tests on turbid media by means of a cross-correlation technique, in which a medium is disposed in an examination container and by means of two laser beams, the point of intersection lies in the examination container, is illuminated, and wherein the light intensity scattered by the laser beams on the crossing point adjusted by means of detection optics and cross-correlated received, and wherein the direction vectors of the two, in each case from an incident beam and the received by a detection optics formed portion of the scattered light intensity litter geometries, are arranged in such a way that they at least one, by means of the point of intersection of the illuminating beams plane extending in the examination container, by an angle are tilted away, characterized in that the illuminating beams (k1, k2) and the direction vectors are arranged in such a way that the two litter geometries in relation to each through the point of intersection of the two crossed be illuminated in the examination container beams (k1, k2) are arranged asymmetrically extending plane, so that the two detection optics at least portions of an equivalent light spots and to discharge the of the two detection optics..
