EYEPIECES FOR AUGMENTED REALITY DISPLAY SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240231111 titled 'EYEPIECES FOR AUGMENTED REALITY DISPLAY SYSTEM
The eyepiece waveguide for an augmented reality display system consists of an optically transmissive substrate, an input coupling grating (ICG) region, a multi-directional pupil expander (MPE) region, and an exit pupil expander (EPE) region.
- The ICG region receives an input beam of light and couples it into the substrate as a guided beam.
- The MPE region includes diffractive features that diffract the guided beam in multiple directions to create diffracted beams.
- The EPE region overlaps the MPE region and out-couples one or more of the diffracted beams from the substrate as output beams.
Potential Applications: - Augmented reality displays - Heads-up displays in vehicles - Medical imaging devices
Problems Solved: - Enhancing the field of view in augmented reality systems - Improving the quality of displayed images - Increasing the efficiency of light transmission
Benefits: - Enhanced user experience in augmented reality applications - Improved visibility and clarity of displayed information - Increased comfort for users wearing the display system
Commercial Applications: Title: Advanced Eyepiece Waveguide for Augmented Reality Displays This technology can be used in: - Consumer electronics for gaming and entertainment - Military and defense for heads-up displays - Healthcare for medical imaging devices

Original Abstract Submitted
an eyepiece waveguide for an augmented reality display system may include an optically transmissive substrate, an input coupling grating (icg) region, a multi-directional pupil expander (mpe) region, and an exit pupil expander (epe) region. the icg region may receive an input beam of light and couple the input beam into the substrate as a guided beam. the mpe region may include a plurality of diffractive features which exhibit periodicity along at least a first axis of periodicity and a second axis of periodicity. the mpe region may be positioned to receive the guided beam from the icg region and to diffract it in a plurality of directions to create a plurality of diffracted beams. the epe region may overlap the mpe region and may out couple one or more of the diffracted beams from the optically transmissive substrate as output beams.
