Paper Abstract
In order to study the influence of variation of the active laser coherence on the intensity correlation imaging, the coherence factor is introduced by the generalized Van Citter-Zernike theorem. Establishing the intensity correlation imaging model based on the variation of coherence, a laboratory experimental platform is designed. Hence, the effect of coherence on spectral modulus can be calculated by using the new model. Then, different phase retrieval algorithms are used to restore the images. The experimental results show that: coherence variation has an effect on the calculated spectral modulus, and the coherence factor can eliminate the effect to a certain extent. The intensity correlation imaging model based on coherence variation can better restore target images, which proved the correctness of the model. Image quality of prior information iteration algorithm is higher than that of hybrid input and output algorithm. The signal-to-noise ratio of reconstructed image is measured to up to be 5.3 dB.
