OPTICAL SYSTEM AND DISPLAY APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18537966 titled 'OPTICAL SYSTEM AND DISPLAY APPARATUS
An optical system in a 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 to allow the light beam to pass through in a specific sequence.
- The light beam travels through the third lens, reflects off the first transmissive reflective surface towards the display surface, passes through the second lens, reflects off the second transmissive reflective surface towards the pupil surface, and finally exits through the first lens to reach the pupil surface.
Potential Applications: This optical system could be used in various display technologies such as augmented reality devices, head-up displays in vehicles, and virtual reality headsets.
Problems Solved: The system helps in efficiently guiding light beams from display surfaces to pupil surfaces, improving the overall viewing experience for users.
Benefits: Enhanced image quality, reduced glare, and improved visibility are some of the benefits of this optical system.
Commercial Applications: This technology could be valuable in the development of advanced display systems for consumer electronics, automotive applications, and medical devices.
Questions about the Technology: 1. How does this optical system improve the viewing experience for users? 2. What are the potential challenges in implementing this technology in different display devices?
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.
