The spontaneous emission spectra of the optical klystron in the storage ring of Hefei were calculated by numerical simulation method combined with the measured magnetic field, taking into account the influence of beam energy dispersion, angular dispersion and position dispersion. In the simulation process of electronic random sampling using statistical averaging. The effects of energy dispersion, angular dispersion and position dispersion on the modulation rate of spontaneous emission are discussed. The influence of the off-axis and oblique incidence of electrons on the spontaneous emission spectrum is calculated. Many important data are obtained, which is of guiding significance to the experiment
