FMCW Lidar Beyond Nyquist by Instantaneous Frequency Fitting
Alfred Krister Ulvog, Joshua Rapp, Vivek K Goyal
Frequency-modulated continuous-wave (FMCW) lidar conventionally estimates distance and velocity from constant beat frequencies generated through interferometry. Existing FMCW imple…

Free-running vs. Synchronous: Single-Photon Lidar for High-flux 3D Imaging
Ruangrawee Kitichotkul, Shashwath Bharadwaj, Joshua Rapp +3
Conventional wisdom suggests that single-photon lidar (SPL) should operate in low-light conditions to minimize dead-time effects. Many methods have been developed to mitigate these…

Dead Time Compensation for High-Flux Ranging
Joshua Rapp, Yanting Ma, Robin M. A. Dawson +1
Dead time effects have been considered a major limitation for fast data acquisition in various time-correlated single photon counting applications, since a commonly adopted approac…
