PROJECTION DEVICE AND COMMUNICATION DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240348752 titled 'PROJECTION DEVICE AND COMMUNICATION DEVICE
The patent application describes a projection device that utilizes a spatial light modulator to modulate the phase of a light beam emitted from a light source, controlled by a control unit to form a desired image. The modulated beam is then reflected by a curved mirror with a curved reflective surface, enlarging the projection angle according to the curvature of the mirror.
- Light source emitting a beam
- Spatial light modulator modulating the phase of the beam
- Control unit setting a phase image for desired image formation
- Curved mirror reflecting the modulated beam on its reflective surface
- Enlarged projection angle based on the mirror's curvature
Potential Applications: - Projection systems for entertainment venues - Holographic displays - Virtual reality and augmented reality applications
Problems Solved: - Enhanced image quality and projection angle - Precise control over phase modulation for accurate image formation
Benefits: - Improved image clarity and resolution - Versatile applications in various industries - Enhanced user experience in entertainment and visualization
Commercial Applications: Title: Advanced Projection Systems for Immersive Experiences This technology can be used in theaters, theme parks, museums, and other entertainment venues to create captivating visual displays. It can also be integrated into virtual reality headsets for immersive gaming experiences.
Questions about the technology: 1. How does the curved mirror impact the projection angle? The curved mirror reflects the modulated beam, enlarging the projection angle based on its curvature. 2. What role does the control unit play in image formation? The control unit sets a phase image for the spatial light modulator to modulate the beam accurately.
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.
