    Broadband terahertz holography using isotropic VO2 metasurfaces by Jiayu Zhao, Runxuan Zhang, Sicheng Cao, Mingwei Zhuang, Zhengyong Song

    Published 2025-01-01
    “…It leverages insulating-to-metallic phase transition of VO2 to enable broadband holography for terahertz wave. For the metallic VO2, the upper VO2 antennas reflect incident terahertz wave and generate hologram. …”

    Complex-valued three-dimensional atomic spectroscopy with Gaussian-assisted inline holography by Xing Huang, Yuzhuo Wang, Jian Zhao, Saijun Wu

    Published 2025-01-01
    “…The convenience of Gaussian propagation helps address key challenges in digital holography. In this paper, we develop a Gaussian-decomposition-assisted approach to inline holography for single-shot, simultaneous measurements of absorption and phase-shift profiles of small atomic samples sparsely distributed in three dimensions. …”

    RFreeTrack: RFID non-contact robust positioning system based on differential phase holography by Linqing GUI, Yi JIANG, Qingyun ZHANG, Fu XIAO

    Published 2024-03-01
    “…To address the issue of large positioning errors in complex environments within non-contact RFID-based positioning systems, RFreeTrack system was proposed.Commercial RFID equipment was used to calculate the reflected signals from targets, achieving high-precision non-contact positioning in complex environment.Firstly, a search method based on time-series similarity was proposed to employ for calibrating static signals, thus significantly enhanced the robustness of target reflection signal extraction.Secondly, a non-contact positioning method based on differential phase holography was introduced to eliminate the influence of the reader antenna’s position, thus the accuracy of positioning was improved and the complexity of system was deployment reduced as well.Finally, a high-precision non-contact positioning system prototype was realized.Experimental results indicate that in complex environments, the phase of the target reflection signals extracted using the calibrated static signals has a 68.8% lower error compared to existing methods.Based on the previously calibrated static reflection signals, the average positioning error using differential phase holography in complex environments is 0.040 8 m, and has a 50.6% improvement on location over existing methods.…”
