实时数字全息法在温度场测量中的应用

Application of the real-time digital holograph in the measurement of temperature field

提出了一种新的光学测量方法,即实时数字全息法。用CCD记录整个过程中的动态干涉条纹,并能用视频文件连续地呈现出物体的实时变化。论文中通过对温度场的测量证明了此方法的准确性,可行性。该方法降低了对环境的要求,能逐步引进到日常生产中。

We proposed a new method of optical measurement, which is called ＂real-time digital holograph＂. We use CCD to record the dynamic interference patterns during the entire process and to show the real - time changes continuously through video files. In this paper, we show the accuracy and feasibility of this method by measuring the temperature field. Moreover, this method is less reliant on the experimental environment. Therefore, it can be gradually introduced into civil production.
