摘要	An improved experiment method in a laboratory for intensity correlation imaging was designed to simplify the experiment processing of the intensity correlation imaging and to obtain measured data close to the actual observation. Firstly, the theory of intensity correlation imaging and its influencing factors on imaging quality were analyzed. Then, the existing intensity correlation imaging method and its disadvantages were discussed. A new experiment of intensity correlation imaging was designed and implemented by using a pseudothermal light and a CCD array, and the theories and characteristics to simulate the intensity correlation imaging by proposed method were introduced. Finally, the data analysis and imaging experiments were performed to verify the feasibility of the method. Experimental results indicate that the proposed method measures well the spatial power spectra of the objects, and the measurement noise mainly distributes in the high frequency region. Moreover, the intensity image of the object can be reconstructed by a phase retrieval algorithm when the signal-to-noise ratio is higher than 20. It concludes that this method preferably realizes the simulation of intensity correlation imaging. In the experiment, the adjustment of the intensity random fluctuation and the parameter of observing baseline are more convenient, so that the object with a small angular diameter is easy to be imaged. , 2015, Chinese Academy of Sciences.
