Abstract
A defined determination of the field of view observed through a surgical microscope is made. To achieve this determination, the relative current position of the plane of the field of view to the position of an object detail of interest is detected in a sighting method with the aid of a position detection system operating according to the laser triangulation principle. As soon as the plane of the field of view and the object detail are coincident, then with the aid of detected optical system data, the position of the object detail with reference to the surgical microscope is determined and, with the detected coordinates of the surgical microscope, the position of the field of view is determined in space. The position detecting system required for this purpose operates on an optical basis and can be integrated into the optics of the surgical microscope.
