Image Left: Molecules diffusing through the excitation volume. 

Image Right: Typical shape of the autocorrelation function of the recorded fluorescence signal. The molecule concentration is inversely proportional to the amplitude of the curve, while their diffusion coefficient is inversely proportional to the characteristic decay time.
