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

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 . 1.1 Motivation 2. TCSPC Lifetime Imaging 2.1. Light Sources Fluorescence Lifetime Imaging requires a pulsed excitation source. Two-photon microscopes use fs pulsed Ti:Sa lasers so The dye Allura Red has also a remarkably short fluorescence lifetime of about 10 ps.

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.

(A) 10 µm and 4 µm microspheres were immersed alone (top and middle panels, respectively) or as a mixture in a clear 3D matrix and the bottom layer was imaged using a 20-fold objective (0.5 NA, 2.1 mm WD). The fluorescence lifetime values amount to 4184 ps (71 ps FWHM) for GOI, 4121 ps (123 ps FWHM) for p-TCSPC and 4049 ps (98 ps FWHM) for the single-channel TCSPC, which corresponds with published results, i.e. 4080 ps . We present a novel, multi-dimensional, time-correlated single photon counting (TCSPC) technique to perform fluorescence lifetime imaging with a laser-scanning microscope operated at a pixel dwell-time in the microsecond range.

The need for measuring fluorescence lifetimes of species in subdiffraction- is that of time-correlated, single-photon counting (TCSPC), which is explained in

1.1 Motivation Fig. 2 Comparison of wide-field intensity and single-photon TCSPC FLIM measurements of small beads using either fluorescence lifetime microscopy or endoscopy through a coherent fiber bundle. (A) 10 µm and 4 µm microspheres were immersed alone (top and middle panels, respectively) or as a mixture in a clear 3D matrix and the bottom layer was This paper presents three ways of adapting existing LSMs with time-correlated single photon counting (TCSPC) fluorescence lifetime imaging (FLIM) systems for NIR FLIM: 1) confocal systems with wideband beamsplitters and diode laser excitation, 2) confocal systems with wideband beamsplitters and one-photon excitation by titanium-sapphire lasers lifetime information is independent of fluorophore concentration, it is a method of choice for functional imaging³. However, several factors have limited the widespread application of FLIM.
