OPTICAL SYSTEM AND IMAGE DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18532148 titled 'OPTICAL SYSTEM AND IMAGE DISPLAY DEVICE
Simplified Explanation
The optical system described in the patent application includes a light guide with a periodic structure that guides image light rays from a display element to a field of view region as a virtual image.
- The periodic structure is formed in the body of the light guide and has periodicity in three predetermined directions intersecting each other within a predetermined plane perpendicular to the thickness direction of the body.
- The structure includes an in-coupling region that divides the image light ray into multiple rays and allows them to propagate in different branch directions within the body, as well as an exit region that allows the rays to emerge towards the field of view region.
Potential Applications
This technology could be used in augmented reality headsets, heads-up displays in vehicles, and other display systems where a virtual image needs to be projected for the user.
Problems Solved
This innovation solves the problem of efficiently guiding image light rays from a display element to a field of view region in a compact and effective manner.
Benefits
The benefits of this technology include improved image quality, reduced size and weight of optical systems, and enhanced user experience in viewing virtual images.
Potential Commercial Applications
Potential commercial applications of this technology include consumer electronics, automotive displays, medical devices, and military equipment.
Possible Prior Art
One possible prior art for this technology could be the use of diffractive optical elements in optical systems to manipulate light rays for various applications.
What materials are used to create the periodic structure in the light guide?
The materials used to create the periodic structure in the light guide are not specified in the abstract. Further details may be provided in the full patent application.
How does the exit region of the periodic structure affect the propagation of image light rays towards the field of view region?
The abstract does not provide specific information on how the exit region of the periodic structure affects the propagation of image light rays. This aspect may be elaborated upon in the detailed description of the patent application.
Original Abstract Submitted
An optical system includes a light guide for guiding an image light ray output from a display element to a field of view region as a virtual image. The light guide includes a periodic structure formed in the body having a plate shape. The periodic structure has periodicity in three predetermined directions intersecting each other within a predetermined plane perpendicular to a thickness direction of the body. The periodic structure includes an in-coupling region dividing the image light ray into a plurality of image light rays and allowing the plurality of image light rays to propagate within the body in a plurality of branch directions including branch directions respectively parallel to the predetermined directions, and an exit region allowing the plurality of image light rays propagating in the plurality of branch directions within the body to emerge from the body toward the field of view region.
