OPTICAL MODULATOR AND IMAGE PROJECTOR BASED ON LEAKY-MODE WAVEGUIDE WITH TEMPORAL MULTIPLEXING - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240094611 titled 'OPTICAL MODULATOR AND IMAGE PROJECTOR BASED ON LEAKY-MODE WAVEGUIDE WITH TEMPORAL MULTIPLEXING
Simplified Explanation
The abstract describes a leaky-mode acousto-optical modulator that can generate visual images suitable for direct viewing without the need for image-forming optics. To expand the field of view of the modulator for visual display applications, a switchable beam redirector, such as a switchable-angle reflector, can be added to provide field of view portions one by one in a time-sequential manner. These portions combine to form a continuous synthetic field of view suitable for wide-angle visual displays.
- Leaky-mode acousto-optical modulator can generate visual images for direct viewing.
- Switchable beam redirector, like a switchable-angle reflector, can expand the field of view in a time-sequential manner.
- Portions of the field of view combine to create a continuous synthetic field of view for wide-angle visual display applications.
- Potential Applications
The technology can be used in wide-angle visual display systems, virtual reality headsets, and augmented reality devices.
- Problems Solved
The innovation solves the limitation of field of view in traditional acousto-optical modulators, allowing for wider visual displays without the need for complex optics.
- Benefits
- Enhanced visual experience with wider field of view - Simplified design without the need for additional image-forming optics
- Potential Commercial Applications
- Entertainment industry for immersive visual experiences - Military and defense for advanced display systems - Medical field for enhanced visualization in surgeries
- Possible Prior Art
One potential prior art could be the use of traditional acousto-optical modulators with limited field of view capabilities.
- Unanswered Questions
- How does the switchable beam redirector improve the field of view in the modulator?
The switchable beam redirector provides field of view portions one by one in a time-sequential manner, allowing them to combine into a continuous synthetic field of view suitable for wide-angle visual displays.
- What are the specific applications in the entertainment industry for this technology?
The technology can be utilized in theme park attractions, immersive theater experiences, and virtual reality gaming setups to provide users with a wider and more engaging visual experience.
Original Abstract Submitted
a leaky-mode acousto-optical modulator may be used to generate visual images suitable for direct viewing, without image-forming optics. to extend a field of view of the modulator to limits suitable for visual displays, the leaky-mode acousto-optical modulator may be equipped with a switchable beam redirector, e.g. a switchable-angle reflector, providing field of view portions one by one in a time-sequential manner. the field of view portions coalesce into a continuous synthetic field of view suitable for wide-angle visual display applications.
