What Does TCSPC Stand For?

TCSPC stands for Time Correlated Single Photon Counting

TCSPC, or Time Correlated Single Photon Counting, is a sophisticated measurement technique used in photonics and optics to accurately determine the time intervals between the detection of single photons emitted from a light source. By recording the arrival times of these photons relative to a reference signal, TCSPC enables high-resolution temporal analysis, allowing for the study of dynamic processes in various fields such as fluorescence microscopy, quantum optics, and single-molecule biophysics. This method is essential for obtaining detailed information about the lifetimes of excited states, molecular interactions, and other time-dependent phenomena.
