1.前言六十年代中迅速发展的激光技术与经典的波前再现法相结合之后,产生了激光全息方法。它除了能摄制出栩栩如生的立体影象之外,还引起了干涉计量术的深刻变化,因而给一些力学量的检测提供了新的途径。工程结构物的位移测定,不仅可用于校核强度或刚度计算的精确性,还常用来直接解决复杂情况下的强度和刚度问题,因而传统的干涉法和波纹法得到了发展,然而利用这些方法必
1. Introduction The rapid development of laser technology in the 1960s combined with the classical wavefront reproduction method resulted in a laser holographic method. In addition to producing lifelike stereo images, it has also led to profound changes in interferometry, which has provided a new avenue for the detection of some mechanics. The displacement measurement of engineering structures can not only be used to check the accuracy of strength or stiffness calculation, but also used to directly solve the problem of strength and stiffness under complicated conditions. Therefore, the traditional methods of interferometry and corrugation have been developed. However, must
