Fluorescence Lifetime Imaging (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.

It uses highly efficient algorithms that can globally fit FLIM data with modest photon numbers to complex decay models, across hundreds or thousands of fields of view, requiring only tens of seconds of processing time on a reasonable desktop computer. TCSPC-FLIM is performed on a confocal laser scanning microscope (CLSM) and so the data is acquired pixel-by-pixel and the histograms of emission photon arrival times, correlated to the laser pulse responsible for each event, are built up for each pixel. 8 flim-general-04.doc January 2017 Fast Online FLIM The bh TCSPC/FLIM systems record and display fluorescence lifetime images at a rate of up to 10 images per second.

The SPC-150NX single photon counting card from Becker and Hickl (B&H) is the highest resolution time correlated single photon counting (TCSPC) card available, offering unsurpassed electrical timing resolution down to 3.3ps full width at half maximum (FWHM) / 1.6ps root mean square (RMS). 2019-05-14 ved by time domain FLIM. TCSPC measurements additionally provide a higher accuracy of multi-exponential decay analysis which is often essential to determine fluorescence lifetimes in the hetero-geneous cellular environment. Finally the TCSPC set up of PicoQuant offers the possibility for other time resolved measurements such as FCS. 2. Phasor FLIM is a very powerful analysis tool for molecular species separation and FRET analysis, in particular when the donor has a multi-exponential lifetime, something which is typical of CFP [cyan fluorescent protein] (Caiolfa et al., 2007).

Imaging techniques based on time-correlated single photon counting (TCSPC), such as fluorescence lifetime imaging microscopy (FLIM), rely on fast single-photon detectors as well as timing electronics in the form of time-to-digital or time-to-analog converters. Conventional systems rely on stand-alone or small arrays (up to 32) of detectors and external timing and memory modules. We recently TCSPC intensity image and FLIM data for lifetime analysis. • Timed – User-defined run time for acquisition, providing TCSPC intensity image and FLIM data for lifetime analysis.

And, it is still unknown on how short can we measure the °uorescence lifetime with the M 1 method in a given TCSPC-FLIM system. In this paper, through numerical simulation and experimental analysis, we investigated the per-formance of the M 1 and the Fitting methods in °uorescence lifetime analysis. We found that the M 1 FLIM by multi-dimensional TCSPC was introduced by Becker & Hickl (bh) in 1996. The speed of FLIM with scanning often exceeds the users requirements and expectations.
