| 摘 要： | 提出了一种新的载波电子散斑干涉的处理方法,该方法将载波所形成的直条纹和包含物体变形信息的弯曲条纹在频域直接比较, 避免了传统载波干涉方法中的载波频率计算和由此带来的误差. 因此在准确程度和方便性方面都有明显改进. 本文在给出理论分析的同时进行了实验验证.

| Abstract: | A new carrier wave electronic speckle method for deformation measurement was proposed. In this method, the deformation was measured by comparing the straight parallel fringes to the carrier wave interferometric fringes in the spatial frequency domain. The calculation of the carrier wave frequency and its induced measurement error are avoided, thus obtaining a higher accuracy. Both the theory and the verifying experiment were presented in this paper. |
