    Spectroscopy Method Looks at Polarization, Not Spectra

    Article obtained from Photonics RSS Feed.

    Researchers at Tampere University and their collaborators have shown how the speed of spectroscopic measurements can be made much faster. By correlating polarization to the color of a pulsed laser, the researchers tracked changes in the spectrum of the light by simple and extremely fast polarization measurements. The method opens new possibilities to measure spectral changes on a nanosecond timescale over the entire color spectrum.

    Spectroscopic measurements usually rely on separating the different color components to different positions, where the spectrum can then be read out by a detector array. While this approach enables a direct inspection of the spectrum, it is rather slow due to the limited speed of the large read-out array….
