Abstract: A front-projection 3D autostereoscopic display system using time-sequencing approach is configured for forming a plurality of perspective views of 3D images of an object or scene in a field of view. The 3D displays system comprises a display component, an optical scanning assembly, a sensor and a controller. The optical scanning assembly includes a first lens array, an optical beam shifting device, an optical projection block and a reflection screen. The reflection screen comprises a second converging lens array and a mirror. In the first and second embodiments of the present invention the reflection screen is made respectively flat or curved. The present invention can be used with a wide range of screen sizes especially for large screens and allows significant reduction or elimination of optical cross-talk and also reduces mechanical complexity of 3D display system.

Abstract: The present invention is directed a switchable optical imaging system and a 3D/2D image switchable apparatus having high functional flexibility in a number of aspects and adaptability to various applications. The present invention is based on generating directional optical beams, transforming these optical beams and projecting transformed optical beams in a field of view to thereby divide the field of view into one or more adjustable viewing zones and to form 2-dimensional (2D) images or perspective views of a 3-dimensional (3D) image of an object or scene therein. The present invention is embodied in the switchable optical imaging system and the 3D/2D image switchable apparatus using the same system.

Abstract: This invention enables the construction of equipment for reproduction of static and moving (live) 3-dimensional stereo representations (3-dimensional display), and is capable of recording and transmitting stereo representations of 3-dimensional objects (scenes). The equipment of the present invention provides to the user comfortable conditions for viewing a volumetric representation without eye strain. The viewing of such 3-dimensional images does not require the use of any supplementary means such as glasses, does not drastically limit the position of the viewer with respect to the display, and allows simultaneous viewing of the 3-dimensional display by many viewers from a sufficiently wide field of view.
