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 ...

Onsite Non-Line-of-Sight Imaging via Online Calibration
IEEE Photonics Journal, 2022 There has been increasing interest in deploying non-line-of-sight (NLOS) imaging systems for recovering objects hidden behind corners. Existing solutions need to calibrate the imaging system using auxiliary apparatus and additional detectors.

Non-line-of-sight imaging over 1.43 km. [PDF]
Proc Natl Acad Sci U S A, 2021 Significance Non–line-of-sight (NLOS) imaging can recover details of a hidden scene from the indirect light that has scattered multiple times. Despite recent advances, NLOS imaging has remained at short-range verifications. Here, both experimental and conceptual innovations yield hardware and software solutions to increase NLOS imaging from ...

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.

Experimental Analysis of Spatial Modulation Systems in Mixed LOS/NLOS Scenarios
IEEE Access, 2022 Spatial modulation (SM) as a multiple-input multiple-output (MIMO) technique is a solution suitable which offers, with low system complexity and cost, improved spectral efficiency compared to single-input-single-output (SISO) systems.

Harris hawks optimization algorithm and BP neural network for ultra-wideband indoor positioning
Mathematical Biosciences and Engineering, 2022 Traditional back propagation neural networks (BPNNs) for ultrawideband (UWB) indoor localization can effectively improve localization accuracy, although there is high likelihood of becoming trapped in nearby minima.

Non-Line-of-Sight Imaging with Picosecond Temporal Resolution [PDF]
Physical Review Letters, 2021 Non-line-of-sight (NLOS) imaging enables monitoring around corners and is promising for diverse applications. The resolution of transient NLOS imaging is limited to a centimeter scale, mainly by the temporal resolution of the detectors. Here, we construct an up-conversion single-photon detector with a high temporal resolution of ~1.4 ps and a low noise
