Fibre laser-sensors have emerged as a promising solution for long-distance sensing, offering high SNR and fine spatial resolution. However, their adoption is constrained by fundamental limitations: ...

Scientists use devices known as frequency comb lasers to search for methane in the air above oil and gas operations and to screen for signs of infection in human breath. A new study could help make ...

An overwhelming majority of handheld devices these days have ambient light sensors built into them. A large percentage of TVs and monitors do, too, and that proportion is growing. The sensors allow ...
