本文给出了一种在双曝光全息干涉计量术中判别变形方向的方法.该方法需在双曝光期间移动全息干板,因而可将其视为一种位错全息干涉术.文中还给出了实验验证. In this paper, we present a method to determine the direction of deformation in a double-exposure holographic interferometer that moves the holographic plate during double exposure and thus treats it as a dislocated holographic interferometer. Experimental verification.
