Holographic interferometry with a reference beam reflected out of the object illumination beam by a small mirror fixed to the object compensates statistical vibrations and object motions caused by rough environments and yields stable interference patterns with sufficient contrast. Based on theoretical investigations of the fringe formation in this case, methods for determining the object motion and deformation are developed. It is shown that zero-order fringes always pass the reference mirror in the reconstructed holographic image when this method is used. The displacement of the reference mirror is determined by an additional object undergoing no motion between the two exposures of a double-exposure hologram.
通过固定在物体上的小镜子将参考光束从物体照明光束中反射出来的全息干涉测量法，可补偿由恶劣环境引起的统计振动和物体运动，并产生具有足够对比度的稳定干涉图样。基于对这种情况下条纹形成的理论研究，开发了确定物体运动和变形的方法。结果表明，当使用这种方法时，零级条纹在重建的全息图像中总是会通过参考镜。参考镜的位移由在双曝光全息图的两次曝光之间不发生运动的附加物体来确定。
