Abstract

In view of the primary mirror of large optical system, the influence of surface error on ratio of scattering loss (RSL) is analyzed. The mathematical model among the root-mean square (RMS) error, the correlation length (l) of autocorrelation function of optical elements and the RSL is established by assuming that the surface error is a stationary Gaussian random process with statistical optics theory and Harvey-Shack scatter theory, and the influence of surface error on RSL with simulation computation is analyzed. It is found that RSL increases almost in exponential form with the increasing of RMS and declines in exponential form with the increasing of the correlation length. The mathematical model agrees with the simulation results very well, which can be used to analyze the influence of RMS and the correlation length on the RSL and provide the support for the further finishing and figuring of the optical surface profile.
