实时全息图的自动计算

Auto-calculation of real-time hologram

用Ａｒ＋激光器作光源，光导热塑料作记录介质，ＣＣＤ—微机系统作探测器，从理论和实验上研究了三个干涉图法的实时全息图的自动计算。该工作不但可以再现被测物体变形的二维等高线，也可以再现其三维变形表面，从而实现变形物体的三维测量。作为实例，测量了压力鼓的变形。

Auto-calculation for real-time hologram of 3-interferogram-method is investigated theoretically and experimentally using Ar + laser as a light source,photoconductor-thermoplastic as hologram recording material,and CCD camera-microcomputer as a detector.2-D contour map can not only be obtained by this work but also 3-D deformed surface of a deformed object can be performed.So that 3-D measurement of a deformed object is realized.As an example the deformation of a pressure drum is measured.
