WebDec 5, 2014 · The frequency-domain FLIM technique requires a modulated light source and a modulated detector. The excitation light is modulated or pulsed in intensity at a certain radio frequency (the blue curve in the figure below). The induced fluorescence emission will mirror this modulation pattern and show, due to the fluorescence decay, a delay in time ... WebAug 13, 2015 · In this work, the construction of the phasor plot using time domain data is discussed, including the effect of the instrument response function (IRF). A deconvolution method in the Fourier space is described. The results obtained are applied to fluorescence decays of aqueous fluorescein (basic form) in the presence of concentrated potassium …
