Abstract
The invention is directed to an arrangement and a method for imaging depth-structured objects and for calibrating the imaging in connection therewith, preferably for generating stereoscopic images from different observation planes at different depth levels of an object. According to the invention, in an optical arrangement for imaging depth-structured objects comprising an entrance pupil, an aperture diaphragm, and a receiver surface positioned in the imaging beam path, at least one optical assembly which is displaceable in axial direction is provided between the aperture diaphragm and the receiver surface, and the displacement of this optical assembly within a predetermined length range causes a change in the focus position while the magnification remains the same. Accordingly, the idea of the invention consists in introducing an optical element between the aperture diaphragm and the receiver surface or using an existing optical element in such a way that the defocusing is compensated through its effect without causing a shifting of the image position.
