Multiple depth planar 3D displays using waveguide reflector array projectors

摘要

A two-dimensional array of linear waveguides includes a plurality of 2D planar waveguide assemblies, columns, sets, or layers, each producing a separate depth plane for the simulated 4D bright field. The linear waveguide may have a rectangular cylindrical shape and may be stacked in rows and columns. Each linear waveguide propagates light along the length of the waveguide, for example, at least partially internally reflected via a planar side wall that reflects to at least a portion of at least one opposing pair. A curved micro-reflector may reflect some modes of light while passing others. The side wall or surface may reflect some modes of light while allowing others to pass. Each curved micro-reflector of any given waveguide contributes to a spherical wavefront at a defined radial distance, and the various layers generate image planes at individual radial distances.
