WAVEGUIDE WITH ANTI-REFLECTION PROPERTIES - A simplified explanation of the abstract
This abstract first appeared for US patent application 18574956 titled 'WAVEGUIDE WITH ANTI-REFLECTION PROPERTIES
The head-mounted display system described in the patent application includes a lens element supported by a support structure. The lens element features a waveguide to couple light from an image source, with the waveguide including a waveguide surface and a grating.
- The grating, which is disposed onto the waveguide surface, consists of rows of three-dimensional, 3D, primitive structures with a height smaller than a wavelength of visible incident light at the surface of the sub-wavelength grating.
- The innovative design of the grating with 3D primitive structures allows for efficient coupling of light from the image source, enhancing the overall performance of the head-mounted display system.
- By utilizing sub-wavelength grating technology, the system achieves high resolution and image quality, providing users with a superior viewing experience.
- The small size of the 3D primitive structures ensures minimal interference with the incident light, resulting in clear and sharp images displayed through the head-mounted system.
- This technology represents a significant advancement in head-mounted display systems, offering improved optical performance and user experience.
Potential Applications: - Virtual reality and augmented reality headsets - Medical imaging devices - Military and defense applications - Gaming and entertainment systems - Industrial and engineering visualization tools
