DISPOSITIF OPTO-MECANIQUE DE PROJECTION D'IMAGES ET D'OBSERVATION EN TROIS DIMENSIONS

摘要

The present invention concerns a device for three-dimensional viewing and image projection. One of the main applications of this invention is the design of microscopes for viewing three-dimensional objects magnified to a high degree. A known projection lens (2) reflects on a double-sided mirror screen (5) the image of an object (1) illuminated through a slit diaphragm (3). Said mirror screen rotates around an axis (YY'), enabling the observer (8) to see the tridimensional image (6) in its inherent colour through a Fresnel-type lens-screen (7). A focussing correction lens (4) serves to correct the optical distortions created by the mirror and to collimate said image.
