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

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. Lifetime Fluorescence Spectrofluorometers. Lifetime fluorescence spectroscopy or time-resolved fluorescence spectroscopy investigates the change in fluorescence over time of a sample when irradiated with UV, visible, or near-IR light.

Correlation . Multichannel detection . Scattering . Afterpulsing Introduction The combination of Time-Correlated Single Photon Count-ing (TCSPC) and Fluorescence Correlation Spectroscopy (FCS), called Fluorescence Lifetime Correlation Spec-troscopy (FLCS), is a method that uses picosecond time- Overview.

We use a TCSPC setup from Picoquant . Using a laser pulsed at 40 MHz ( PDL-800-B ), the light intensity is reduced to the level where the photomultiplier detects a photon only after 1% of laser pulses ( i.e. , count rate <0.4 MHz).

This type of measurement is advantageous as it requires low excitation light levels, it is oblivious to donor concentration, and in addition it provides information about the ratio of interacting versus non-interacting proteins Figure 2: TCSPC setup for fluorescence lifetime imaging (FLIM). The TCSPC module receives the timing pulse, the PMT channel number, and the scan clock signals (frame sync, line sync and pixel clock) from the scanning unit of the microscope. For each photon, the TCSPC module determines the location within the scanning area (x and y) and the time Time-correlated single photon counting (TCSPC) is a powerful method to accurately measure the fluorescence lifetime of samples. We use a TCSPC setup from Picoquant .

Time-correlated single-photon counting (TCSPC) is a well established and common technique for fluorescence lifetime measurements, it is also becoming increasingly important for photon migration measurements, optical time domain reflectometry measurements and time of flight measurements. 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 Fluorescence Lifetime Imaging by Multi-Dimensional TCSPC Advanced Techniques and Applications A fluorescence lifetime imaging (FLIM) technique for biological imaging has to combine near-ideal photon efficiency, recording of the full fluorescence decay profiles in the … Performing an FCS Measurement with an Olympus FV1200 upgrade kit.
