PROJECTION DEVICE AND COMMUNICATION DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18683284 titled 'PROJECTION DEVICE AND COMMUNICATION DEVICE
The patent application describes a projection device that utilizes a spatial light modulator and a curved mirror to project an image with an enlarged projection angle.
- Light source used in the projection device
- Spatial light modulator modulates the phase of the emitted beam
- Control unit sets a phase image for desired image formation
- Curved mirror reflects the modulated beam to enlarge projection angle
Potential Applications: - Projection systems for entertainment venues - Augmented reality displays - Holographic displays in museums or exhibitions
Problems Solved: - Enlarging projection angles for better visibility - Enhancing image quality and clarity in projections
Benefits: - Improved image projection quality - Enhanced viewing experience for audiences - Versatile applications in various industries
Commercial Applications: Title: Advanced Projection Systems for Enhanced Viewing Experiences This technology can be used in theaters, theme parks, and educational institutions to provide immersive visual experiences for audiences. The market implications include increased demand for high-quality projection systems in entertainment and educational sectors.
Prior Art: Researchers can explore patents related to spatial light modulators, curved mirrors, and projection devices to understand the existing technologies in this field.
Frequently Updated Research: Researchers are constantly working on improving spatial light modulators and curved mirrors to enhance image projection quality and expand the applications of projection devices.
Questions about Projection Devices: 1. How does the spatial light modulator affect image quality in projection devices? The spatial light modulator plays a crucial role in modulating the phase of the emitted beam, which directly impacts the clarity and resolution of the projected image.
2. What are the key differences between traditional projection systems and the innovative device described in the patent application? The innovative projection device combines a spatial light modulator and a curved mirror to enhance image quality and enlarge projection angles, offering a significant improvement over traditional projection systems.
Original Abstract Submitted
A projection device that includes a light source, a spatial light modulator including a modulation portion irradiated with a beam emitted from the light source, the spatial light modulator modulating a phase of the emitted beam in the modulation portion, a control unit that sets a phase image for forming a desired image in the modulation portion of the spatial light modulator, and controls the light source in such a way that the modulation portion, in which the phase image is set, is irradiated with the beam, and a curved mirror having a curved reflective surface irradiated with a modulated beam modulated by the modulation portion of the spatial light modulator, the curved mirror reflecting the modulated beam on the reflective surface, and projecting a projection beam having a projection angle enlarged according to a curvature of the reflective surface.
