High resolution single-photon imaging for recognition of camouflaged target

Single-photon LiDAR offers single-photon sensitivity and picoseconds timing resolution, leading to high-resolution images. In this paper, we investigate the reconstruction of depth and intensity profiles from data acquired using a custom designed time-of-flight scanning transceiver based on the time-correlated single-photon counting LiDAR. The system comprises a pulsed laser source at 1064nm wavelength, a monostatic scanning transceiver and a Si single-photon detector. The experimental result is present for reconstruction of high resolution depth and intensity profiles of targets obscured by camouflage at a distance of 425m in daylight. A total variation restoration optimization algorithm is performed to restore profiles of targets, and the results show that it maintains image quality for multi-depth targets while reducing acquisition times.
