Adaptive Headlamps in Automobile: A Review on the Models, Detection Techniques, and Mathematical Models

IEEE Access, 2021
Driving at night with traditional headlamps poses significant threats, with many accidents occurring during the night because of temporary blindness caused by the headlights of the oncoming traffic.

Laser-excited single crystal phosphor in white LED for wide field of view and high enhanced central brightness for vehicle headlights

AIP Advances, 2022
We demonstrate the generation of a laser hotspot by a laser-excited single crystal phosphor (SCP) converter layer in a white LED for producing a wide field of view (FOV) and high enhanced central brightness (ECB) for an adaptive-driving-beam (ADB ...

InTEn-LOAM: Intensity and Temporal Enhanced LiDAR Odometry and Mapping

Remote Sensing, 2022
Traditional LiDAR odometry (LO) systems mainly leverage geometric information obtained from the traversed surroundings to register lazer scans and estimate LiDAR ego-motion, while they may be unreliable in dynamic or degraded environments.

Laser-assisted LED for adaptive-driving-beam headlights employing ultra-reliable single crystal phosphor for autonomous vehicles

Optics Express, 2021
A novel laser-assisted LED for adaptive-driving-beam (ADB) headlights employing an ultra-reliable Ce3+: YAG-based single crystal phosphor (SCP)-converter layer for use in autonomous vehicles is demonstrated. The SCP fabricated at a high-temperature of 1,940°C exhibited better thermal stability than other phosphor-converter materials, evidenced by a ...

Polarization‐resolved femtosecond Vis/IR spectroscopy tailored for resolving weak signals in biological samples using minimal sample volume

FEBS Open Bio, EarlyView.
Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐
