摘　　要：提出了辅镜全息三维振动分析的新技术，论述了辅镜时间平均全息干涉图的光强分布规律，阐明了该技术在作三维振动分析时的解法以及借助于准同位辅助物体全息术提取参考光虚点光源振幅信息的方法，从理论上分析了辅镜全息干涉图的零级明纹位置问题．A new technique of using auxiliary-mirror holography to analyse 3D vibration is Proposed. The intensity distribution of the auxiliary-mirror time-averaged holographic interferogram is discussed. The solution in which the above holographic technique is used to measure the 3D amplitude and the method which draws information of the virtual point sources of the refcrence beaxns with the help of quasi-same-position auxiliary-object holography are explained. The Problem of the position of the zero order bright fringe of the auxiliary-mirror time-averaged holographic interferogram is analysed in theory.
