Measurement of Photon Count Rate Based on Broad-Band Parametric Down-Conversion
In order to realize the calibration of photoelectric detector at continuous and broad-band based on correlated photon, it is necessary to investigate distribution of the correlated photon spectra and photon count rate. By simulating distribution rule of the correlated photon spectra and photon count rate, an experimental system is set up to measure the spectra distribution and the photon count rate distribution of continuous and broad-band correlated photon. The spectra distribution and the photon count rate during 450~710 nm are measured by using the system. Strict consistency is revealed by comparing theory simulation results with experimental ones, and the correlated coefficient is 99.39%. The results show that correlated photon have continuous and broad-band range. It can be applied to direct the calibration of quantum efficiency of photoelectric detector at continuous based on correlated photon in theory and experiment.
