We have demonstrated better than 10 pm spectral resolution in remote spectroscopy of plumes generated by UV filaments on solid targets [J-C Diels. Projecting high power density at long distance for standoff spectroscopy. In SCIentific eXchange SCIX conference 2017, Laser induced breakdown spectroscopy, Reno, Nevada, 2017.]
A new type of spectrometer for remote sensing is being developed. The Sagnac Fourier Spectrometer (SAFOS) combines compactness, high resolution and large input aperture [M. Lenzner and J.-C. Diels. A Sagnac Fourier spectrometer. Optics Express, 25:A447{A453, 2017.].
