OPTICAL SYSTEM AND OBSERVATION APPARATUS HAVING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 18061521 titled 'OPTICAL SYSTEM AND OBSERVATION APPARATUS HAVING THE SAME
Simplified Explanation
The patent application describes an optical system that can create an enlarged image of a display surface using a combination of reflective surfaces.
- The optical system consists of a first half-transmissive reflective surface and a second half-transmissive reflective surface, arranged in a specific order.
- Light from the display surface passes through the second half-transmissive reflective surface, reflects off the first half-transmissive reflective surface, reflects off the second half-transmissive reflective surface again, and then passes through the first half-transmissive reflective surface.
- The light is then directed towards the exit pupil, which is the point where the observer's eye is positioned.
- Additionally, there is a second optical path where light from the exit pupil passes through the first half-transmissive reflective surface, then through the second half-transmissive reflective surface, and finally reaches an image sensor.
Potential applications of this technology:
- Enlarged image display: The optical system can be used in devices such as projectors or head-mounted displays to create larger and more immersive visual experiences.
- Teleconferencing: By using this optical system, video conference participants can view a larger image of the remote participants, enhancing the sense of presence and communication.
Problems solved by this technology:
- Enlarged image formation: The optical system solves the problem of creating an enlarged image of a display surface without distorting the image or losing clarity.
- Compact design: The arrangement of the reflective surfaces allows for a more compact and efficient optical system, making it suitable for various devices.
Benefits of this technology:
- Enhanced visual experience: The optical system provides an enlarged image, improving the visual experience for the observer.
- Compact and efficient design: The arrangement of the reflective surfaces allows for a more compact and efficient optical system, making it suitable for integration into various devices.
- Improved communication: In applications like teleconferencing, the enlarged image can enhance communication by providing a clearer and more immersive view of remote participants.
Original Abstract Submitted
An optical system is configured to form an enlarged image of a display surface of an image display element and includes, in order from a side of an exit pupil to a side of the display surface, a first half-transmissive reflective surface and a second half-transmissive reflective surface. The optical system has a first optical path on which light from the display surface transmits through the second half-transmissive reflective surface, is reflected by the first half-transmissive reflective surface, is reflected by the second half-transmissive reflective surface, transmits through the first half-transmissive reflective surface, and is guided to the exit pupil, and a second optical path on which light from the side of the exit pupil transmits through the first half-transmissive reflective surface, transmits through the second half-transmissive reflective surface, and is guided to an image sensor.
