Near-Eye Optical Layout Using Polarization and Angle Selection

The patent introduces polarization dimension and angle selection to control light paths, allowing the system to achieve a larger field of view without increasing the physical distance between light source and optical apparatus. By manipulating light in the polarization and angular domains rather than solely expanding physical space, the system resolves the contradiction between field of view and device thickness.

The patent employs polarization units and angle selection units as intermediary elements that mediate between the light source and the final image formation. These intermediaries control and redirect light paths, enabling effective image amplification within a compact thickness by optimizing light utilization without requiring increased physical distance.

The patent applies different optical properties to different parts of the light path through polarization units and angle selection units. By locally controlling light transmission and reflection characteristics at specific positions and angles, the system achieves complete field of view coverage without requiring a uniformly large light inlet, thus maintaining compact overall thickness.

The patent changes the polarization state and incident angle parameters of light as it passes through different units. By dynamically adjusting these optical parameters rather than relying solely on a large fixed light inlet, the system captures all lights in the field of view while maintaining a compact device thickness.
