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 TCSPC process builds up photon distributions over these times and the scan coordinates [4, 11, 13, 15, 16] The TCSPC principle is shown in Fig. 3. A fluorescence lifetime image is obtained by building up a photon distribution over the times, t, of the photons in the laser pulse period, and the scanner position, x, y, during the Tonperiods.

This short lifetime does not depend on the emission (observation) wavelength (from 550 nm to 750 nm) and it is another candidate for impulse response measurements. Fluorescence-lifetime imaging microscopy or FLIM is an imaging technique based on the differences in the exponential decay rate of the fluorophore from a sample. . It can be used as an imaging technique in confocal microscopy, two-photon excitation microscopy, and multiphoton tomograp We present a fluorescence lifetime imaging technique with simultaneous spectral and temporal resolution.

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. We present a fluorescence lifetime imaging technique with simultaneous spectral and temporal resolution. The technique is fully compatible with the commonly used multiphoton microscopes and nondescanned (direct) detection. An image of the back‐aperture of the microscope lens is projected on the input of a fiber bundle. A new Time-Correlated Single Photon Counting (TCSPC) imaging technique delivers combined intensity-lifetime images in a two-photon laser scanning microscope. The sample is excited by laser pulses Fluorescence Lifetime.

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.

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. We present an approach which monitors both time- and spectral information of the fluorescence in order to receive the full information content of the light emitted from a sample.
