Hyperspectral Imaging using In-Line Interferometric Femtosecond Stimulated Raman Scattering — •Sven Dobner and Carsten Fallnich — Institute of Applied Physics, Westfälische Wilhelms-Universität, Corrensstr. 2, 48151 Münster

We present the hyperspectral imaging capabilities of in-line interferometric femtosecond stimulated Raman scattering (II-FSRS [1]). The beneficial features of this method, namely the improved signal-to-background ratio compared to other applicable broadband stimulated Raman scattering methods and the simple experimental implementation, allow for a rather fast acquisition of three-dimensional raster-scanned hyperspectral datasets. A subsequent application of a principle component analysis displays the chemical selectivity of the method.
