    Laser-Based Sensor Simplifies, Improves Benzene Detection Capabilities

    Article obtained from Photonics RSS Feed.

    Researchers from King Abdullah University of Science and Technology (KAUST) have developed a laser-based device capable of sensing extremely low concentrations of benzene. The sensor works in real time, helping monitor benzene emission levels.

    The sensor, developed by a team led by Aamir Farooq, features walls that consist of two parallel, concave mirrors. The mirrors are positioned to face one another, forming a cavity around a gas sample. The cavity traps a laser beam, which repeatedly reflects off the mirrors. The two-mirror system enables the laser beam to travel across a distance (through the sample) that is significantly larger than the distance it would travel in a system featuring inter-mirror separation.

    The system…
