用实时全息法分析多层陶瓷复合传感器的表面法向位移量当复合传感器在受激励后，表面上各点相对受激励前的状态会产生位移，从而形成干涉条纹用摄像机记录这个过程，利用像分离器把干涉图像传输到计算机中，按像元的位置和强度以一定格式存储对存储图像的处理过程如下：数字化、滤波、二进制处理、筛选、定级后分成不同二维像矩阵库，从而进行数值和形象化处理最后的矩阵生成表面位移量的三维投影图本文所提供的两幅三维位移图，是同一复合材料的两个不同位置传感器受激励前后的位移变化所测得的最大法向位移为１３２９ｎｍ Real-time holographic analysis of multilayer ceramic composite sensor surface normal displacement  When the composite sensor is stimulated, the surface of each point relative to the state prior to being stimulated displacement will be generated to form interference fringes  recorded this process with a video camera, Using a splitter to transfer the interference image to the computer, the location and intensity of the pixel are stored in a certain format. The process of storing the image is as follows: digitization, filtering, binary processing, screening and ranking are divided into different two- Library for numerical and visualization  The final matrix generated surface displacement of the three-dimensional projection  The two-dimensional displacement map provided in this article, is the same composite materials at two different position sensor before and after the excitation of the displacement change  The measured maximum normal displacement of 1329nm
