A Single-Shot Non-Line-of-Sight Range-Finder [PDF]
Sensors, 2019 The ability to locate a target around a corner is crucial in situations where it is impractical or unsafe to physically move around the obstruction. However, current techniques are limited to long acquisition times as they rely on single-photon counting ...

Non-line-of-sight imaging [PDF]
Nature Reviews Physics, 2020 Emerging single-photon-sensitive sensors combined with advanced inverse methods to process picosecond-accurate time-stamped photon counts have given rise to unprecedented imaging capabilities. Rather than imaging photons that travel along direct paths from a source to an object and back to the detector, non-line-of-sight (NLOS) imaging approaches ...

Deep Non-Line-of-Sight Imaging Using Echolocation [PDF]
Sensors, 2022 Non-line-of-sight (NLOS) imaging is aimed at visualizing hidden scenes from an observer’s (e.g., camera) viewpoint. Typically, hidden scenes are reconstructed using diffused signals that emit light sources using optical equipment and are reflected ...

Fast back-projection for non-line of sight reconstruction [PDF]
ACM SIGGRAPH 2017 Posters, 2017 Recent works have demonstrated non-line of sight (NLOS) reconstruction by using the time-resolved signal frommultiply scattered light. These works combine ultrafast imaging systems with computation, which back-projects the recorded space-time signal to build a probabilistic map of the hidden geometry. Unfortunately, this computation is slow, becoming a

Time-of-arrival–based localization algorithm in mixed line-of-sight/non-line-of-sight environments
International Journal of Distributed Sensor Networks, 2020 A novel time-of-arrival–based localization algorithm in mixed line-of-sight/non-line-of-sight environments is proposed. First, an optimization problem of target localization in the known distribution of line-of-sight and non-line-of-sight is established,

Ultrasound synthetic aperture non-line-of-sight imaging [PDF]
Communications PhysicsNon-line-of-sight (NLOS) imaging typically relies on the use of ultrashort laser pulses and time-resolved detection to then reconstruct 3D environments that are hidden from the direct line-of-sight.

Non-line-of-sight tracking of people at long range [PDF]
Optics Express, 2017 A remote-sensing system that can determine the position of hidden objects has applications in many critical real-life scenarios, such as search and rescue missions and safe autonomous driving. Previous work has shown the ability to range and image objects hidden from the direct line of sight, employing advanced optical imaging technologies aimed at ...
