    Abstract     

        I will introduce a robust cosmic shear measurement method based on the Fourier transformation of galaxy image. The method can systematically remove the shear measurement bias due to the point spread function, the background noise, the source Poisson noise, etc.. I will give a detailed description of this method, and show some of the results achieved with the data from the GREAT3 competition.
