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.

(a) Time-lapse of 3D Cerulean fluorescence images of neuronal processes in the brain stem of a CerTN L15 mouse as acquired by p-TCSPC FLIM. λ exc = 850 nm, z step-size = 2 µm, λ detection = 475±20 nm, peak laser power 3.13·10 5 mW. 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 new generation of the bh DCS-120 FLIM system features unprecedented temporal resolution, unprecedented timing reproducibility, high spatial resolution, h During imaging¶. Keep peak *pixel* count rates below at least 5% of repetition rate. Understand pulse pileup effects; Consider image fill factor when monitoring count rate SPC-150NX TCSPC FLIM Module. 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).

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. We have combined picosecond wide‐field TCSPC FLIM with lightsheet microscopy.
