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 ...

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 ...

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 Transient Rendering
Jornada de Jóvenes Investigadores del I3A, 2022 Non-line of sight imaging reconstructs hidden geometry using time-resolved measurements of indirect diffuse reflections emitted by a laser. To help develop new applications, we simulate light transport in these occluded scenes and introduce a set of simple, yet effective subpath sampling techniques for efficiency, with an open-source implementation.
