An arrangement for generating a stereoscopic image of an object for viewing by an observer includes an imaging optic for imaging the object and defining an imaging beam path as well as an entry pupil and an exit pupil. Illuminating optics illuminate the object by providing an imaging beam coming from the object and passing through the imaging optic and along the imaging beam path. The imaging beam is sectioned in the imaging beam path into two component beams at one of the following locations: in the exit pupil, near the exit pupil or at a position along the imaging beam path which is optically conjugated to the exit pupil, thereby forming stereoscopic sectioned images. The stereoscopic section images are allocated in a clocked manner to the left and the right eyes of the observer. The invention is also directed to a method of generating a stereoscopic image of the object.

Method for generating a stereoscopic image of an object and an arrangement for stereoscopic viewing

An arrangement for generating a stereoscopic image of an object for viewing by an observer includes an imaging optic for imaging the object and defining an imaging beam path as well as an entry pupil and an exit pupil. Illuminating optics illuminate the object by providing an imaging beam coming from the object and passing through the imaging optic and along the imaging beam path. The imaging beam is sectioned in the imaging beam path into two component beams at one of the following locations: in the exit pupil, near the exit pupil or at a position along the imaging beam path which is optically conjugated to the exit pupil, thereby forming stereoscopic sectioned images. The stereoscopic section images are allocated in a clocked manner to the left and the right eyes of the observer.

The invention is directed to a method and arrangement for generating stereoscopic images of an object. The method includes the steps of illuminating an object with an illuminating beam; masking the illuminating beam to generate a first component beam to illuminate the object at a first angle and provide a first image of the object to a first viewing eye; again masking the illuminating beam to generate a second component beam to illuminate the object at a second angle and to provide a second image of the object to a second viewing eye; and, alternately repeating the last two steps at a frequency above the flicker frequency of the human eye. In the arrangement of the invention, a beam generating device alternately generates first and second illuminating beam components which illuminate the object via illuminating optics at respectively different angles to produce respective images of the object. A directing device for alternately directing the images to the left and right eyes of a viewer at a frequency above the flicker frequency of the human eye.
