| 摘 要： | 提出了一个新的测量物体三维形变量的系统.其中,光源部分由3个激光器组成,参考物被粘贴在压电陶瓷(PZT)相移器上,通过该相移器产生参考光并实现相移,物光和参考光通过放置在CCD前方的大剪切棱镜产生干涉.为了验证该系统的可行性,对简支梁进行了位移场的测量,并给出了实验结果.由于大剪切方棱镜采用普通玻璃材料制成,因此不仅克...

| Abstract: | A new three-dimensional(3-D) electronic speckle pattern interferometry(ESPI) system is constructed by using three ESPI systems,a large shearing blocky prism and a reference.In the system,the light source was composed of three lasers,and the reference was attached to the PZT phase shifter.At the same time,the PZT phase shifter could be used to generate a reference light and push reference plane to change optical path of reference light.Then the object light interfered with the reference light through a large... |
