RETINAL PROJECTION DISPLAY DEVICE AND PHASE PROFILE OPTIMIZATION METHOD THEREOF - A simplified explanation of the abstract
This abstract first appeared for US patent application 18117122 titled 'RETINAL PROJECTION DISPLAY DEVICE AND PHASE PROFILE OPTIMIZATION METHOD THEREOF
Simplified Explanation
The abstract describes a retinal projection display device that uses a combination of light sources, spatial light modulators, holographic optical elements, and field lenses to create a display that focuses complex wavefronts onto the retina.
- Light source emits light
- Spatial light modulator diffracts emitted light
- Holographic optical element reflects diffracted light by duplicating it into multiple complex wavefronts
- Field lens focuses complex wavefronts onto focal points in an eye-box
- Complex wavefronts overlap each other
Potential Applications
- Virtual reality and augmented reality displays
- Heads-up displays in vehicles and aircraft
- Medical imaging and visualization
- Gaming and entertainment systems
Problems Solved
- Provides a compact and lightweight display solution
- Offers a wide field of view and high resolution
- Minimizes eye strain and fatigue by focusing light directly onto the retina
Benefits
- Enhanced user experience with immersive and realistic visuals
- Improved portability and comfort for extended use
- Enables precise and accurate visualization of complex data
- Reduces the need for bulky and cumbersome display equipment
Original Abstract Submitted
A retinal projection display device is provided. The retinal projection display device includes a light source configured to emit light, a spatial light modulator configured to generate diffracted light by diffracting the emitted light, a holographic optical element configured to reflect the diffracted light by duplicating the diffracted light into a plurality of complex wavefronts, and a field lens configured to focus the plurality of complex wavefronts to a plurality of respective focal points in an eye-box, wherein the plurality of complex wavefronts overlap each other.
