Webb27 sep. 2024 · Abstract : ruby has a red spectacular fluorescence under violet or blue-green radiations with a doublet spectrum at 692.80 and 694.30 nm, which appears as a single line. In this post we study the fluorescence of ruby and in particular its lifetime. We show that interesting results can easily be … Read More » WebbLaser spectral imaging techniques (single-pixel imaging, hyperspectral, resonance fluorescence spectroscopy, etc.) are important tools for studying the interaction between light and matter. They add one-dimensional spectral information to the ordinary two-dimensional spatial imaging by using the absorption or radiation properties of … graf vehicle inspection
