Researchers have shown how spectroscopic measurements can be made much faster. By correlating polarization to the color of a pulsed laser, the team can track changes in the spectrum of the light by ...

Astronomers report the rapid transition of WOH G64 from a red supergiant to a yellow hypergiant, based on photometric and spectroscopic observations published in Nature Astronomy.

Ultrafast laser spectroscopy allows the ascertainment of dynamics over extremely short time scales, making it a very useful tool in many scientific and industrial applications. A major disadvantage is ...

Ellipsometry is a total optical measurement technique. This method is employed to measure how the polarization of light changes when passing through a medium. The polarized light shows distortion ...

Soft sensors are powerful tools that can be used along with spectroscopic instruments in on-line measurement. Process analytical technology (PAT) is helping process engineers to better understand and ...

Consumers in developed countries rarely think about the authenticity of their food and drink. Perhaps they should, as the threat from fake foods is real and the potential health ramifications dire.

Researchers at Tampere University and their collaborators have shown how spectroscopic measurements can be made much faster. By correlating polarization to the colour of a pulsed laser, the team can ...

The Ellipsometry is a total optical measurement method. This technique is used to measure the change of polarization of light when passing through a medium. Due to the layer structure during ...
