Experimental study on spatial coherence of soft X-ray beam from Hefei synchrotron radiation source has been carried out. A spot, that is distribution of optical field, was recorded by positive photoresist (PMMA) located at object plane under the condition of a condenser zone plate which center wavelength is 3. 2nm and a pinhole of 30μm diameter combination. The diameters of Airy diffraction pattern and spatial coherence area were obtained from the spot. In addition, a double slit interference experiment has also been carried out. These experiments are in a good agreement with the calculation estimates.
