Fluorescence Lifetime Imaging Microscopy (FLIM) produces an image based on the differences in the excited state decay rate from a fluorescent sample. Thus, FLIM is a fluorescence imaging technique where the contrast is based on the lifetime of individual fluorophores rather than their emission spectra. FLIM does not depend on concentration, absorption by the sample, sample thickness, photo-bleaching and/or excitation intensity it is more robust than intensity based methods.
