FLIM by multi-dimensional TCSPC is based on scanning the sample by a high-repetition rate pulsed laser beam and the detection of single photons of the fluorescence signal returning from the sample.

The key advantage of frequency-domain FLIM is its fast lifetime image acquisition making it suitable for dynamic applications such as live cell research: the entire field of view is excited semi-continously - using relatively broad excitation pulses - and read out simultaneously. 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. • Streaming to HDF5 file – TCSPC data can be streamed, for a user-determined time period, to a HDF5 file.

Technical Realization Time-Correlated Single Photon Counting (TCSPC) is used to determine the fluorescence lifetime. In TCSPC, one measures the time between sample excitation by a pulsed laser and the arrival of the emitted photon at the detector[1], [2]. TCSPC requires Figure 5 b: Decay from just one of 24,578 SPAD pixels demonstrates the very high resolution and TCSPC fidelity of FLIMera. FLIM and HORIBA. The novelty of the in-pixel detection and timing technology enables a widefield imaging approach, which significantly reduces data acquisition times enabling the study of dynamic events.

Fluorescence Lifetime Imaging (FLIM) in life sciences based on ultrashort laser scanning microscopy and time-correlated single photon counting (TCSPC) started 30 years ago in Jena/East-Germany.

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.

the mean arrival times of the photons after the laser pulse. When not defined otherwise, intensity and color scale stretch from minimum to maximum. The FLIM systems are based on bh's multi-dimensional time-correlated single photon counting (TCSPC) process in combination with confocal or multiphoton scanning by a high-frequency pulsed laser beam.
