当前全息干涉计量总的发展趋势是光电结合以提高测量精度,利用计算机处理数据作定量计算提高速度.近几年来.笔者在这方面作了一些尝试.本文介绍借助于对双曝光全息图作多次观察来测定物体三维位移场的一种快速算法.由于处理方法的一般性,这种快速算法不仅可用于研究固体力学、精密机械,还可用于生物医学(例如口腔矫形、全息牙科术、骨胳变形及颅脑外伤等)的基础研究和临床实践. At present, the general trend of holographic interferometry is photoelectric combination to improve the measurement accuracy, and the use of computer processing data for quantitative calculation to increase speed.In recent years, the author made some attempts in this regard.In this paper, with the help of double exposure hologram A fast algorithm for determining the three-dimensional displacement field of an object Due to the general nature of the processing method, this fast algorithm can be used not only to study solid mechanics, precision machinery, but also to biomedical applications such as orthopedics, holographic dentistry, Deformation and traumatic brain injury, etc.) basic research and clinical practice.
