Abstract
For object detection, particularly in fluidic microsystems, optical imaging of at least one resting or moving object ( ) on a structured mask ( ) with at least one segment from a flat section ( ), in which the object ( ) is located at least partially or temporarily and which has a characteristic dimension smaller than the dimension of the object ( ) or its movement path, to a detector unit, detection of the quantity of light transmitted by the structured mask ( ), and generation of a detector signal which has a predetermined relationship with the quantity of light, and evaluation of the detector signal in regard to the presence of the object ( ), its position, its shape and/or the temporal change of the position are performed.
