Depth‐enhanced light field camera system based on focus‐tunable geometric phase lens module
Abstract We propose an active‐switching light‐field (LF) camera system that significantly extends the measurable depth range over conventional passive‐optics‐based LF systems by integrating a stacked geometric phase lens (GPL) module in a compact design. During elemental image acquisition and LF rendering, chromatic aberration in the focus‐tunable GPL is compensated by adjusting the reconstruction depth and magnification for each color channel. Additionally, the optimal GPL operation sets are selected based on color‐dependent depth‐of‐focus conditions. These optimizations enable the proposed GPL‐based LF system to achieve full‐color, depth‐enhanced LF imaging while mitigating the typical trade‐off between spatial resolution and depth of field limitations.
