The digital phase conjugation technology is used to investigate the optical field recovery characteristics in scattering media. The scattering medium is treated as a plane of phase and amplitude random modulation, the optical field recovery effect under three different modulation conditions is deduced theoretically, and a numerical simulation is performed. The results show that optical fields can be ideally recovered for the pure phase modulation or the Gaussian amplitude random phase modulation with a Gaussian curve wide enough. In pure phase modulation, higher wavefront recording precision and larger aperture size will result in better recovered optical fields. The optical field recovering can accommodate some noise, and the intensity recovering is more robust to noise than the phase recovering.
