Theoretical background along with experimental results are given for a simple method for in-plane fringe enhancement in dual-beam illumination holographic interferometry. In this method, the fringes representing in-plane displacements arise as a moirépattern between two interferograms. To distinguish the in-plane displacement, a sequence of images is recorded while the reference mirror is continuously tilted at random. The in-plane fringes arethen found as the maximum contrast of the out-of-plane fringes in the image sequence. The resulting fringe quality is close to the quality of the out-of-plane fringes.
给出了双光束照明全息干涉术中一种用于面内条纹增强的简单方法的理论背景及实验结果。在该方法中，代表面内位移的条纹作为两个干涉图之间的莫尔条纹出现。为了区分面内位移，在参考镜连续随机倾斜时记录一系列图像。然后，将面内条纹确定为图像序列中面外条纹的最大对比度。所得条纹质量接近于面外条纹的质量。
