Purpose of the Study:
- To develop a transparent autostereoscopic display.
- To demonstrate the superposition of 3D data onto the real world.
- To achieve wearable-free 3D visualization.
Main Methods:
- Utilized laser picoprojectors and a wedge light guide.
- Optically recorded a holographic optical element.
- Developed a prototype display system.
Main Results:
- Successfully created a transparent autostereoscopic display.
- Demonstrated the capability to superimpose 3D data onto real-world environments.
