METHOD FOR DETECTING MAGNETICALLY MARKED OBJECTS AND CORRESPONDING DEVICE

Magnetically marked objects, in particular biological objects, such as cells, are continuously detected by moving at least one magnetically marked object in a magnetic field, measuring a local change in the magnetic field caused by the magnetically marked object, generating a signal, in particular a digitized signal, based on the measured local change in the magnetic field, conditioning the generated signal by at least one convolution of the generated signal using a mathematical function, and evaluating the conditioned signal. The evaluation of the signal includes determining extreme values, in particular maximum values, of the signal and comparing the determined extreme values with a threshold value, in particular a predefined threshold value, which, if exceeded, indicates detection of the object.
