Abstract

A fluorescence detection system for testing a sample having at least one fluorophore. The fluorescence detection system comprises a white light generation system outputting a white light pulse. The white light pulse has a first frequency range and a first time duration. The white light pulse excites the at least one fluorophore of the sample to emit a fluorescence. The fluorescence has a second frequency range and a second time duration, wherein the first time duration is less than the second time duration. A time-resolving detector receives the fluorescence and at least a portion of the white light pulse and separates the fluorescence from the portion of the white light pulse.
