ABSTRACT:
Method and device for determining one or more Z distances from an object surface to a reference plane, for example the primary plane of the primary objective of a microscope. By projecting an optical pattern onto an object, and subsequently detecting and computationally evaluating the object's reflection of this pattern by means of an image processing unit, it is possible to obtain relief-like imaging of the object and to identify the individual Z distances, irrespective of the object's contouring.
