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 sky above 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...
