OPTICAL SYSTEM AND DISPLAY APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240248321 titled 'OPTICAL SYSTEM AND DISPLAY APPARATUS
The optical system described in the patent application is designed to direct a light beam from a display surface to a pupil surface using a series of lenses and reflective surfaces.
- The system includes a first lens with a transmissive reflective surface facing the display surface, a second lens, and a third lens with a transmissive reflective surface facing the pupil surface.
- A quarter waveplate is positioned on the pupil surface side of the second lens.
- The second lens and the third lens are spaced apart from each other.
- The light beam travels through the third lens and then the second lens, is reflected by the first transmissive reflective surface towards the display surface, passes through the second lens, is reflected towards the pupil surface by the second transmissive reflective surface, and finally enters the pupil surface.
Potential Applications: - This optical system could be used in augmented reality or virtual reality headsets to enhance the display quality and user experience. - It may also find applications in medical devices, cameras, and other imaging systems where precise control of light beams is required.
Problems Solved: - The system helps in efficiently guiding light beams from a display to a pupil surface, ensuring optimal image quality and clarity. - It addresses the challenge of managing light reflections and transmissions within an optical system.
Benefits: - Improved image quality and brightness in display systems. - Enhanced user experience in viewing digital content. - Precise control and manipulation of light beams for various applications.
Commercial Applications: Title: Advanced Optical System for Enhanced Display Quality This technology could be utilized in the development of high-end augmented reality headsets, medical imaging devices, advanced cameras, and other optical systems requiring precise light control. The market implications include improved product performance, increased user satisfaction, and potential advancements in various industries.
Questions about the technology: 1. How does this optical system compare to existing technologies in terms of efficiency and performance? 2. What are the potential cost implications of implementing this system in commercial products?
Original Abstract Submitted
an optical system is configured to guide a light beam from a display surface to a pupil surface, and includes, in order from a pupil surface side to a display surface side, a first lens having a first transmissive reflective surface on the display surface side, a second lens, and a third lens having a second transmissive reflective surface on the pupil surface side. a quarter waveplate is provided to a surface on the pupil surface side of the second lens. the second lens and the third lens are spaced apart from each other. the light beam from the display surface transmits through the third lens and the second lens in this order, is reflected by the first transmissive reflective surface toward the display surface, transmits through the second lens, and is reflected toward the pupil surface by the second transmissive reflective surface, transmits through the second lens and the first lens in this order, and enters the pupil surface.
