Study of Periodic Intensity Profiles by Fourier Transform of the Time-interval Probability Measurement: Application to Lifetime Measurements

Abstract In this paper a general study is made to find out the possibility of obtaining information about a periodic intensity profile from the measurement of the Fourier transform of the time-interval probability (FT-TIP). It is found that information can be obtained for small intensities. FT-TIP is then applied to fluorescence decay spectroscopy and it is shown, by a computer simulation method, that lifetimes can be measured with small errors for very small intensities.
