Near-infrared spectroscopy, or fNIRS, offers a way to monitor brain activity without surgery or radiation by tracking changes in blood flow and oxygenation. Light sources placed on the scalp send near ...

Recognizing the features and benefits of each type of light sensor will allow for the proper selection in specific requirements. The three most common photodetectors are the photomultiplier (PMT), the ...

Atmospheric Light Detection and Ranging (LIDAR) is widely used in aviation and aeronautic applications. LiDAR applications are not only used as tools for scientific studies but also to improve flight ...

The Spectra optical caries detection device by Air Techniques is a useful adjunct for detecting, assessing, and monitoring enamel demineralization and caries progression, according to the product's ...

Electro-optical detectors are used to measure or sense the radiation emitted or reflected by objects within the detector’s optical field of view (FOV). Passive systems operate without any illumination ...

Super-sensitive imaging systems cover new ground. In the near future, laser-based detection systems will allow military aircraft to identify enemy ground vehicles accurately in battle zones and permit ...

A research team led by Pasquale Scarlino at EPFL has built a small, tunable detector capable of sensing individual microwave ...

A novel technique for enhancing optical spring that utilizes the Kerr effect to improve the sensitivity of gravitational wave detectors (GWDs) has recently been developed. This innovative design uses ...
