Illumination of a random diffuse object by a fringe pattern produced by two symmetrical laser beams leads to phenomena that are usually studied with speckle interferometric techniques. We first show that these phenomena are analogous to moiré. We then propose to apply this method for measuring the transverse vibrations of a diffuse surface in real time with interferometric sensitivity. Further, we show that the discussed system can work as a linear displacement transducer; the theoretical aspects of this so-called random moire transducer are investigated.
由两束对称激光束产生的条纹图案对随机漫射物体进行照明会导致一些现象，这些现象通常用散斑干涉技术进行研究。我们首先表明这些现象类似于莫尔条纹。然后我们建议应用这种方法以干涉测量灵敏度实时测量漫射表面的横向振动。此外，我们表明所讨论的系统可以用作线性位移传感器；对这种所谓的随机莫尔传感器的理论方面进行了研究。
