In this paper an annular aperture method for laser speckle photography is proposed. The autocorrelation of an annular aperture function is calculated.The intensity distributions of the diffraction halos single exposure speckle patterns recorded by annular apertures with various internal to external diameter ratios ?(? = 0, 1/2, 3/4, 5/6, 7/ 8)are given, and these distributions are normalized by total diffraction intensity. It is shown that the intensity distribution of the diffraction halo is of rotational symmetry and the intensity at the border of the diffraction halo is increased remarkably,while the intensity at the intermediated region of the diffraction halo may be on a fairly high lever when an annular aperture with an appropriate ratio 77 is used. Therefore not only filtering in all directions at the border of the diffraction halo can be carried out to achieve isothetics with high sensitivity along arbitrary direction, but also the widest variable sensitivity region can be obtained.

本文提出了用环形孔径光阑进行激光散斑照相的方法,对这种方法进行了理论分析和实验验证.结果表明,选用适当的环形孔内径和外径比η,可使散斑图的衍射晕边缘光强明显增强,而又保证中间部分仍有一定的光强。这样,既可在整个衍射晕边缘任意方向滤波,得到高灵敏度的、沿任意方向的等位移分量条纹,又可获得最宽的灵敏度变化范围。在逐点分析时可明显提高衍射晕边缘条纹的对比度,因而能提高测量的准确度。此外,散斑图的记录时间一般比多孔径的短得多。

This paper puts forward a method of taking a laser speckle pattern interferential photograph recorded by two apertures (an annular and biannular aperture). It gives more homogeneous diffraction halo of distribution of light intensity and better Young's fringes image.

本文提出了用两个孔径(单环和双环孔径)装置进行激光散斑干涉照相的方法,得到了光强分布比较均匀的衍射晕和较好的杨氏条纹照片.

提出用双环孔径记录进行激光散斑照相的方法。结果表明,采用这种方法不仅提高了散斑图衍射晕边缘的光强,同时和环形孔径法相比,使腰部的暗区消失了,提高了测量的准确度,图片质量较好。
