Abstract
A fluorescence average excited-state lifetime sensor and sensing method comprising a fluorescence excitation light source, light-directing apparatus directing light from the light source to a sample, light-receiving apparatus receiving fluorescence light generated by the sample, and a narrow-band resonance amplifier providing gain necessary to support self-oscillations in an opto-electronic loop comprising the light source, the sample, the light-directing apparatus, the light-receiving apparatus, and the resonance amplifier.
