【摘要】 本文提出了一种测量物体位移矢量方向的方法一参考物体全息法 ,该方法将一个参考物体置于被测物体的一侧 ,然后在一张干版上记录两个双曝光全息图 :一个是受到干版位移调制的被测物体和参考物体的双曝光全息图 ,一个是被测物体的非调制干涉图。前者用于测量位移矢量的方向 ,后者用于测量被测体位移的数值场。文中主要介绍了参考物体全息法测量位移矢量方向的原理。文后给出了实验结果。更多还原

【Abstract】 Measuring displacement direction of object by reference-object holographic method is proposed.The reference-object is put on a side of the measured object.Two double exposure holograms of two objects are recorded in the same plate.One is the hologram of the measured object and the reference object modulated by plate displacement.The other is non-modulated hologram of the measured object and reference object.The former is used to analyze direction of displacement vector of measured object.Latter is used to measure value of displacement vector.The principle of the measuring direction of displacement Vector is described.Experimental results are given.更多还原
