Single-shot Double-Field of View Polarization Holography

What we believe to be a novel approach of quantitative polarization digital holography that simultaneously captures polarization-resolved information across a double field of view (FOV) is proposed and experimentally demonstrated. By integrating polarization-sensitive detection with a spatial multiplexing strategy, the method enables the acquisition of two distinct holographic scenes within a single exposure-each with independent spatial coverage and polarization contrast. This configuration allows for vectorial imaging while effectively extending the system's spatial observation range without compromising temporal resolution. The measurement accuracy and imaging performance of the proposed double FOV polarization-sensitive digital holography are confirmed on anisotropic materials, and the outcomes support its applicability. The technique offers significant advantages for applications requiring wide-area monitoring with polarization sensitivity, such as biomedical imaging, material characterization, and remote sensing. Experimental demonstrations validate the system's ability to reconstruct full-Stokes parameters across both FOVs with high fidelity, opening a new avenue for efficient, real-time polarization imaging across extended spatial domains.
