M 1 can also be interpreted as the average arrival time of all photons within a TCSPC measurement. It is thus linearly related to the time-constant of a single-exponential sample response, e.g. the lifetime of a single-exponential fluorescence

For this purpose both optical events are converted into electrical puls-es. For the fluorescence photon this is done via the single photon detector mentioned before. General layout for fluorescence lifetime measurements To determine the lifetime of a fluorophore, time-correlated single photon counting (TCSPC) is a well-known and established method. In this setup, a pulsed laser excites the desired sample and the emitted photons are collected by a detector.

Tcspc fluorescence lifetime

25 October 2006 Multiwavelength fluorescence lifetime imaging by TCSPC.

The principle of TCSPC is the detection of single photons and This paper describes a time-correlated single photon counting (TCSPC) technique for picosecond resolution multi-wavelength lifetime imaging in two-photon or confocal laser scanning microscopes and other scanning systems. The technique uses a four-dimensional histogramming process that records the photon density versus the time within the fluorescence decay function and the x-y coordinates of Other than life time measurements, the technique is being successfully used for single molecule detection, TCSPC imaging, and fluorescence correlation spectroscopy in combination with fluorescence microscopy etc.}, author = {Akhtar, Mohammad Bilal}, language = {eng}, note = {Student Paper}, title = {Fluorescence Lifetime Measurement using Time Correlated Single Photon Counting}, year = {2010}, } Graphical abstract A compact liquid-core waveguide time-correlated single-photon counting (LCW-TCSPC) sensor for fluorescence lifetime measurement (FLM) is presented.

TCSPC is based on light behaving as quanta (photon). TCSPC has many applications other than fluorescence lifetime measurement, such as Ultrafast recording of optical waveforms, Detection and Identification of Single Molecules, DNA sequencing, Optical Tomography, and Fluorescence lifetime imaging .
