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…
Seeing Around Corners with Edge-Resolved Transient Imaging
Joshua Rapp, Charles Saunders, Julián Tachella +7
Non-line-of-sight (NLOS) imaging is a rapidly growing field seeking to form images of objects outside the field of view, with potential applications in search and rescue, reconnais…
Estimation from Quantized Gaussian Measurements: When and How to Use Dither
Joshua Rapp, Robin M. A. Dawson, Vivek K Goyal
Subtractive dither is a powerful method for removing the signal dependence of quantization noise for coarsely-quantized signals. However, estimation from dithered measurements ofte…
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…
A Few Photons Among Many: Unmixing Signal and Noise for Photon-Efficient Active Imaging
Joshua Rapp, Vivek K Goyal
Conventional LIDAR systems require hundreds or thousands of photon detections to form accurate depth and reflectivity images. Recent photon-efficient computational imaging methods…
