Fluorescence spectroscopy (also known as fluorimetry or spectrofluorometry) is a type of electromagnetic spectroscopy that analyzes fluorescence from a sample. It involves using a beam of light, usually ultraviolet light, that excites the electrons in molecules of certain compounds and causes them to emit light; typically, but not necessarily, visible light. A complementary technique is absorp… WebApr 12, 2024 · This paper describes a single-shot fluorescence lifetime imaging (FLIM) method. We use an optical cavity to create temporally delayed and spatially sheared replicas of the fluorescent decay signal onto a time-gated intensified charged-coupled device (iCCD). This modality allows different portions of the decay signal to be sampled in parallel by ...
