ABSTRACT:
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.
