Diagram showing laser filamentation and remote spectroscopic detection of the back-scattered light. A method for remotely detecting pollutants and other chemicals in the atmosphere has been demonstrated by physicists at the Massachusetts Institute of Technology, using laser-generated jets of plasma. Their laboratory experiments could pave the way to instruments used to monitor pollution levels...

Illustration of photoacoustic tomography New research demonstrates the use of a pulsed laser diode in photoacoustic tomography, a technique that uses light pulses to generate sound waves in a sample, which are then detected by an ultrasound detector and from which images can be produced computationally. Due to the higher pulse rate of...

Beam of light in the sky above a city A new approach to atmospheric monitoring measures laser backscatter range as a function of angle using the Scheimpflug principle, instead of the more common time of flight method known as Lidar, which means it can monitor a large volume of space all at once. Given the name SLidar, it was...
