    Abstract

    In this paper, we propose three new basic apertures in rotating aperture method: rectangle-located-aperture and parallelogram-located-aperture and right-triangle-located-aperture. Theoretical analysis and experimental demonstration are presented. By using these new apertures, the utilization ratio of information of a specklegrain is increased, the intensity distribution of diffraction halo becomes more reasonable and the N/S ratio is enhanced, so the speckle fringes are clearer and the experimental errors are less.
