News image18 December 2014
An infrared spectrometer has been sent into space as part of a new mission to analyse an asteroid approaching Earth

Mirror keeps buildings cool by sending infrared radiation into space

News image17 December 2014
Stanford University researchers in the USA have developed a coating to keep buildings cool in a more energy-efficient way. By using a technique referred to as radiative active cooling, the ultrathin material reflects infrared radiation

Waterproof near-infrared spectrometer monitors swimmers' performance

11 December 2014
A waterproof spectrometer capable of measuring muscle oxygenation underwater has been developed by scientists in the UK. The device, which has been described in the Journal of Biomedical Optics, would be beneficial for swimmers monitoring their performance

Spectroscopy method diagnoses bone diseases early

4 December 2014
Research published on the 28 November described a Spatially Offset Raman Spectroscopy (SORS) technique which, for the first time, was able to detect brittle bone disease by simply scanning the patient's limbs

Frequency combs measure greenhouse gases over a two-kilometre path

News image6 November 2014
Laser frequency combs have been used to monitor the concentrations of greenhouse gasses over a distance of two kilometres. The technique was demonstrated by the National Institute of Standards and Technology in collaboration with the National Oceanic and Atmospheric Administration

Laser technology used to detect biogas leaks from metres away

News image5 November 2014
Fraunhofer scientists have developed a laser-based system that can detect methane leaks in biogas plants from up to 15 metres away. The device is based on optical emission and backscattering spectroscopy
