摘要
本文提出一种新的三维位移测量方法:标针投影全息干涉法.列出了此方法的计算公式、分析了理论误差,并选用悬臂梁作实验验证. 本方法已应用于牙基托中前部断裂原因的分析.
In this paper a new method for measuring 3-D displacements, needle projection method with holographic interferometry, is developed. The calculating formulas are provided, the theoretic errors are analyzed, and the experimental verification is made with a cantilever beam.
This method can apply to analyze cracking on the center-front of upper denture.
