| 摘要 |
The invention relates to a method for quantitatively and/or qualitatively detecting particles in liquid, wherein the liquid to be examined is arranged in a beam path of an optical device between at least one light source and an image capture sensor having a matrix of light-sensitive cells, wherein the pixel values of the cells are detected and the distribution of the pixel values is determined at least in part, and wherein the pixel value or values determined most frequently are used as a value or as an average value for a background signal, wherein, upon reaching a predetermined threshold for the background signal, a signal is emitted or the method is interrupted. |
