OPTICAL IMAGING SYSTEM AND 3D DISPLAY APPARATUS

摘要

An optical imaging system and related 3D display apparatus for forming different perspective views of a 3 -dimensional image by transforming optical beams emanating from pixels located on a display pixel surface displaying 2-dimensional patterns and projecting the transformed optical beams in a field of view is disclosed herein, The optical imaging system comprises: an array of selecting light guide elements for reducing a radiating aperture of each pixel; a lens array of converging micro-lenses; a displacement mechanism for moving the lens array relative to the array of light guide elements in a respective plane: and a sensor system for sensing the position of the lens array relative to the array of light guide elements, The lens array together with the array of light guide elements are configured to provide at least one viewing zone in the field of view and form respective perspective views in each viewing zone by projecting therein the transformed optical beams.
