Typical Application

Photon Correlation Measurement

ST1010(P) can be used for the measurement of correlated photon pairs, which is an important means of quantum optics research such as quantum secure communication and single photon generation. PPLN or PPKTP crystals can be pumped by pump light to generate associated photo pairs , which are measured by single photon detectors after split by PBS or 50/50 BS and the counting signals are analyzed by TSCPS to obtain associated information.

Fluorescence Lifetime Measurement

The fluorescence lifetime is usually on the order of ps~us, and TCSPC is the most mature and accurate test method for measuring such a short time. A synchronous signal source is used to drive the laser, the outgoing light pulse irradiates the sample cell and the fluorescence signal is detected by a photon detection device (mostly PMT),and each photon counting signal is in F.

TOF Application

TOF(Time of Flight) measurement refers to a means of obtaining information such as relative distance or particle mass by measuring the flight time of photons(or particles), One of its typical applications is laser ranging ,using picosecond (or femtosecond) lasers to generate light pulses and using BS to separate part of the signal at the laser exit and restore it to electrical pulses as reference signals, the light pulse is reflected at the measured object, the time difference of the reference signal and the echo signal corresponds to the distance of the measured object.
