| contents | Quantum imaging employs the nonclassical correlation of photons to break through the noise limitation of classical imaging, realizing high sensitivity, high SNR imaging and multifunctional image processing. To enhance the flexibility and imaging performance of the optical systems, metasurfaces composed of subwavelength structural units provide a powerful optimization approach, enabling advanced applications in quantum state modulation and high-precision imaging. Conventional phase contrast imaging is fundamentally constrained by its single-phase modulation scheme, precluding adaptive switching between imaging modalities. Therefore, the development of high-contrast imaging techniques that can be used in any combination of phases has been a challenge in the field of optical imaging. Here, we propose a novel imaging scheme combining a polarization-entangled light source and a polarization multiplexed metasurface, which realizes remotely switchable bright-dark phase contrast imaging, demonstrating the flexibility and high integration of the system. Experiments show the system can realize high contrast and high SNR imaging under low phase gradient conditions (phase difference as low as π/5) and exhibit excellent phase resolution. In addition, the system is suitable for imaging biological samples under low-throughput light conditions, providing an efficient and non-destructive shooting solution for biomedical imaging and promoting the development of phase-sensitive imaging technology. |
