Full-Stokes polarimetric imaging light detection and ranging (LiDAR) provides rich information about distance, materials, texture, surface orientations, profiles of objects, it is an important remote-sensing technology. One major challenge to reach a long distance efficiently collect detect the echo photons, as for long-range LiDAR, photons may become sparse. Here, we demonstrate full-Stokes working at eye-safe, telecommunication wavelength 1560 nm, that can range 4 km. The key enabling technology four-channel system with multimode-fiber-coupled, large-area fractal superconducting nanowire single-photon detectors. Furthermore, also explore faster (e.g., pixel-dwell time 1 ms) objects shorter approximately Our demonstration has significantly extended LiDAR represents step toward practical systems enable many applications in remote sensing recognition targets.
