High-Flux Array Laser Imaging Based on Photon Waveform Recovery (Invited)
Yihua Hu, and Ahui Hou
Single-photon light detection and ranging (LiDAR) is constrained by the first photon bias effect, which requires the use of low photon flux to avoid signal distortion. This results in longer detection times, and requirements for rapid detection and imaging are not met. In this study, we propose a single-photon array im
