Phonon Mean Free Path Spectroscopy By Raman Thermometry
Katharina Dudde, Mahmoud Elhajhasan, Guillaume Würsch +6
In this work, we exemplify on a bulk silicon sample that Raman thermometry is capable of phonon mean free path (PMFP) spectroscopy. Our experimental approach is similar to the vari…

Hyperspectral near infrared imaging using a tunable spectral phasor
Jan Stegemann, Franziska Gröniger, Krisztian Neutsch +7
Hyperspectral imaging captures both spectral and spatial information from a sample. The near infrared (NIR, > 800 nm) is advantageous for biomedical imaging as it falls into the ti…
