photon counting

photon counting
single-photon detectors (SPD), TCSPC, time-correlated single photon counting, detection of individual photons, photosensors

Whether in astrophysics, materials science, quantum information science, quantum encryption, medical imaging, DNA sequencing, or in fiber-optic communication: Single-photon detectors (SPD) provide a timing signal from which, for example, fluorescence lifetimes of excited matter can be deduced (FLIM). This is the perfect job for our TDCs and in some applications already our "entry-level"-device can be employed.
