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 ...

Measuring the velocity field of a fluid flow, such as air or water, allows for greater feedback and control, something that could boost the performance and fuel-efficiency of aircraft. A research ...

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 ...
