The effect of the near-field intensity distribution on linear phase retrieval is analyzed in detail. Reconstructed results in cases of three distributions-tilt, ring, random-type near-field intensity distribution are compared with uniform intensity respectively. The results show that the reconstructed effect of tilt-type which is composed of odd functions is adverse; while the reconstructed effect of ring and random-type which is composed of even functions is not large. Especially when the spatial frequency was higher, the reconstructed effects are smaller. In addition, near-field intensity and phase obtained from atmospheric turbulence distortion are simulated by using the linear phase retrieval algorithm. Near-field intensity distribution of the results have influence on the reconstruction, but the influence is not too great.
