实验表明，在全息干涉计量中，漫射照明影响条纹的可见度函数，因此，条纹对比度依赖于条纹的阶数。这一性质可用于二次曝光全息干涉计量中条纹级数局部极小值的识别。该方法已用于识别双脉冲全息干涉术中歌手皮肤振动的节纹。
It is experimentally shown that the diffuse illumination in holographic interferometry influences the visibility function of the fringes and, as a result, the fringe contrast depends on the fringe order. This property can be applied to identification of the local minima of fringe order in double-exposure holographic interferometry. The method has been used in identifying the nodal pattern of a singer’s skin vibrations in double-pulse holographic interferometry.
