AI Technical Summary
Conventional wearable three-dimensional displays using light-guide optical elements (LOE) systems can only project a single depth plane focused at infinity, lacking the capability to simulate a four-dimensional light field, which limits the depth perception and realism of the displayed images.
A wave guide reflector array projector (WRAP) system is employed, comprising a stack of thin, planar 2D wave guides with embedded curved micro-reflectors that project multiple virtual depth planes at different radial distances, simulating a 4D light field by using a 2D array of linear wave guides with angularly oriented micro-reflectors to create a spherical wave front, allowing for a more realistic 3D experience.
The WRAP system enables the projection of multiple depth planes, enhancing depth perception and creating a realistic 3D effect by mimicking the psycho-physical properties of a real 3D object or scene, providing a more immersive display experience.
