Abstract
The invention relates to a method and a device for the optical in vitro detection of a movement in a biological sample and/or for the optical in vitro detection of a movement of a component of the biological sample. The method has the following step: (a) providing an optical wide-field illumination device for illuminating the sample, said device being designed to illuminate the entire sample, and a detector () for detecting radiation () coming from the sample. The detector () has a detection surface () which is divided into multiple detection regions (). The detector is additionally designed to derive (S) detection signals () of individual detection regions () with respect to time, subsequently rectify (S) the signals, preferably by generating an absolute value or squaring, and summing or averaging (S) the derived and rectified detection signals of all of the detection regions and then providing same as an output signal (). The method further has the steps of illuminating the sample using the wide-field illumination device and detecting a movement in the biological sample on the basis of the output signal () of the detector ().
