OPTICAL SYSTEM AND HEAD-UP DISPLAY SYSTEM COMPRISING SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 18423722 titled 'OPTICAL SYSTEM AND HEAD-UP DISPLAY SYSTEM COMPRISING SAME
Simplified Explanation
The patent application describes an optical system that includes a display emitting a light flux recognized as an image by an observer, and a light guide body replicating the light flux through diffraction by a diffraction structure in the expansion region of the light guide body.
- The light flux is expanded and replicated in both horizontal and vertical directions corresponding to the image recognized by the observer.
- The coherence length of the diffracted light flux in the expansion region is smaller than twice the distance between the diffraction structure and the front or back surface of the light guide body.
Potential Applications
This technology could be applied in:
- Head-up displays in vehicles
- Augmented reality devices
Problems Solved
- Improved image quality in optical systems
- Enhanced visibility for observers

Original Abstract Submitted
An optical system includes a display that emits a light flux visually recognized by an observer as an image, and a light guide body that replicates the light flux. The light flux is emitted from the emission surface after being expanded by being replicated in a first direction corresponding to a horizontal direction of the image visually recognized by the observer due to diffraction by a diffraction structure of an expansion region in the light guide body, a second direction corresponding to a vertical direction of the image, or both the directions. A coherence length of the light flux diffracted and emitted in the expansion region in the light guide body is smaller than twice a shorter interval between the diffraction structure and each of a front surface and a back surface of the light guide body.
