Head-Mounted Display Lens Portion Expanding Field of View

The optical system is divided into multiple lens groups (first lens group with multiple lenses, second lens group, and condenser) instead of using a single lens. Each lens group performs specific optical functions to collectively expand the field of view while managing system complexity through functional segmentation.

Multiple lens groups are nested within the optical system in a hierarchical structure where the first lens group processes light initially, the second lens group further processes the refracted light, and the condenser collects the final refracted light. This nested arrangement allows systematic expansion of optical capabilities.

The microlens system is segmented into multiple discrete lens groups rather than using a single complex microlens array. The first lens group contains multiple individual lenses, each handling specific portions of the light field, which simplifies the overall design while achieving expanded field of view.

The optical system extends light processing in multiple spatial dimensions by arranging lens groups at different positions and orientations. The first lens group processes light in one dimensional arrangement, while the second lens group and condenser process light in subsequent dimensional layers, collectively expanding the field of view.

The second lens group acts as an intermediary between the first lens group and the condenser. It receives light refracted by the first lens group and prepares it for collection by the condenser, ensuring that even light rays at larger angles are properly directed and maintained for efficient collection.

The optical system employs parameter optimization where the focal lengths and lens pitches of different lens groups are specifically designed to work together. By adjusting these parameters, the system maintains efficient light collection across a broader angular range, accommodating larger outermost ray angles while preserving light gathering efficiency.
