Waveguide Displays

• Mechanism: Light is directed through transparent materials, allowing images to be projected directly into the user’s eyes. This technology enables a slim profile and often provides a wider field of view (FOV).
• Examples: Microsoft HoloLens 2 and Magic Leap 1.

Reflective Displays

• Mechanism: These displays project images onto a reflective surface, such as a prism or lens, which then directs the light to the user’s eyes. They tend to be less immersive but more practical for specific applications.
• Examples: Google Glass and Epson Moverio.

Holographic Displays

• Mechanism: Holography creates three-dimensional images that are viewable from multiple angles, enhancing depth perception and realism.
• Examples: Emerging holographic technologies are still in development stages but hold promise for future AR applications.

2. Field of View (FOV)

• Importance: The FOV determines how much of the augmented content is visible to the user at any time. Wider FOVs enhance immersion and usability.
• Comparison: Waveguide displays generally offer wider FOVs (around 50-52 degrees) compared to reflective displays (typically 20-30 degrees).

3. Resolution and Clarity

• Resolution: High resolution is crucial for clear, detailed images. This is especially important in AR, where digital content is overlaid on the real world.
• Clarity: Optical designs must minimize distortions and aberrations to provide a clear view of both real and augmented content.

4. Optical Distortion and Correction
