This means that the measured fluorescence response is that coming directly from the fluorophore. However, in reality this will not be the case. TCSPC is a statistical method requiring a high repetitive light source to accumulate a sufficient number of photon events for a required statistical data precision. TCSPC electronics can be compared to a fast stopwatch with two inputs. The clock is started by the START signal pulse and stopped by the STOP signal pulse. Time-correlated single photon counting (TCSPC) is a common technique to measure fluorescence decays in the time domain. In principle, single photon events are detected and their time of arrival is correlated to the laser pulse, which was used for excitation of the sample.

The quTAG is a high-end, easy-to-use time-to-digital converter and time tagging device designed for time correlated single photon counting (TCSPC). It is capable of detecting events with a digital resolution of 1 picosecond and a jitter under 10 ps RMS. TCSPC is a time domain technique. Data is accumulated, presented and analysed in a format showing signal intensity versus time, usually in picoseconds, nanoseconds, or microseconds.

However, in reality this will not be the case. PicoQuant is known as a company leading in the field of pulsed diode lasers, time-resolved data acquisition, single photon counting and fluorescence instrumentation.

The system measures luminescence lifetimes ranging over 11 orders of magnitude, and eliminates the need for changing cards or cables. TDCs formed by ring oscillators are arrayable, scalable, and low power, making them suitable for SPAD-based TCSPC 3D imaging systems.

Most of the commercial systems use a method called time-correlated single photon counting (TCSPC), which measures the timing between single photon signals at a photodetector (typically a photo-electron multiplier tube) and laser pulses. The compilation below is probably not complete. If you are the maintainer of a software that deals with TCSPC data please edit this page and add your software listing. Alternatively you can also use https://support.picoquant.com to contact PicoQuant support to submit your software project. A TCSPC system is usually used to record the time-of-flight profile in a brain activity monitoring system.

Looking for online definition of TCSPC or what TCSPC stands for? TCSPC is listed in the World's largest and most authoritative dictionary database of abbreviations and acronyms The Free Dictionary

For each photon, the TCSPC module determines the location within the scanning area (x and y) and the time of the photon in the laser pulse sequence (t). actually do TCSPC with single molecules. Sufficient-ly attenuating the light, so that the detector receives only single photons, has the same effect. Indeed, in order to use TCSPC we must attenuate the light to this level. One may ask now, if we do have light from many molecules, why waste it by attenuation and use TCSPC? TCSPC can be used to measure lifetimes ranging from approx. 5ps to over 50ms (over 7 orders of magnitude).

2018-03-08 · Especially, the TCSPC-based laser ranging system is very suitable for the airborne LiDAR which is usually about 10 km above the ground, because the portable and compact semiconductor laser sources
