Mass along the Line of Sight to the Gravitational Lens B1608+656: Galaxy Groups and Implications for H_0 [PDF]
, 2005 We report the discovery of four groups of galaxies along the line of sight to the B1608+656 gravitational lens system. One group is at the redshift of the primary lensing galaxy (z = 0.631) and appears to have a low mass, with eight spectroscopically ...

Non-line-of-sight propagation in object localization: a survey
Gong-kuang zidonghua, 2020 Due to the existence of obstacles, none-line-of-sight(NLOS) propagation is common in localization scenes like mines, which causes refraction, reflection, diffraction and scattering of localization signals, leads to the increase of ranging error, and ...

Compressed sensing for active non-line-of-sight imaging.
Optics Express, 2021 Non-line-of-sight (NLOS) imaging techniques have the ability to look around corners, which is of growing interest for diverse applications. We explore compressed sensing in active NLOS imaging and show that compressed sensing can greatly reduce the ...

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.

WiFi Access Points Line-of-Sight Detection for Indoor Positioning Using the Signal Round Trip Time
Remote Sensing, 2022 The emerging WiFi Round Trip Time measured by the IEEE 802.11mc standard promised sub-meter-level accuracy for WiFi-based indoor positioning systems, under the assumption of an ideal line-of-sight path to the user. However, most workplaces with furniture

Modeling the X-ray light curves of Cygnus X-3. Possible role of the jet [PDF]
, 2012 Context: Physics behind the soft X-ray light curve asymmetries in Cygnus X-3, a well-known microquasar, was studied. AIMS: Observable effects of the jet close to the line-of-sight were investigated and interpreted within the frame of light curve physics.
