Single photon counting system can recognize and extract weak light signals by pulse discrimination and digital counting technologies,based on the characteristic that photon detector outputs discrete electronic signals under weak irradiation. To discuss and analyze single photon counting system deeply and thoroughly,the working principle of using the impulse amplitude analyzer and photon counter in single photon counting system to measure number of photons is analyzed. The causes which possi?blly affect the accuracy and result in error are discussed. The curves of the experimental data are fitted with the software Matlab.
