摘要
文章采用反射式高灵敏度离面云纹干涉法测量了铁电陶瓷的离面位移。在铁电陶瓷上复制了每毫米1200位相型闪耀光栅的试件栅;采用迈克尔逊干涉光路、全息干版照相、CCD摄像机及其微机实时图像处理系统获取了试件表面的离面位移场的干涉条纹图。
The reflective high sensitivity moire interferometry was applied to measure out of plane displacement fields in ferroelectric ceramics. A phase type blazed specimen grating of 1200 lines/mm was replicated on the surface of the ferroelectric ceramics; the Michelson interferometer arrangement, the holographic plate, moire fringe real time processing system with CCD and personal computer was adopted to collect and process the moire fringe, and to calculate out of plane displacement fields.
