Abstract: An isolated microlens array (I‐MLA) light‐field architecture incorporating gradual radius lens (GRL) design is proposed for realizing a wide‐field autostereoscopic floating 3D display in a compact form factor. The system integrates two key techniques: extended coding pitch combined with directional mesh (DM) for substantial crosstalk suppression and a GRL array with radially varying microlens curvature to enhance image quality at large viewing angles, thereby enabling a wide‐field light‐field system. Optical simulations demonstrate that the fully integrated design achieves a practical continuous viewing angle of 40° (±20°) at a viewing distance of 500 mm—more than fivefold improvement over conventional light‐field displays—while preserving image fidelity with minimal degradation across the entire field of view. This work establishes the proposed I‐MLA architecture incorporating the GRL as a highly effective solution for realizing wide‐field, multiuser autostereoscopic floating 3D displays while maintaining a compact system thickness.
