散斑干涉法 meaning in English

espi
speckle interferometry

Speckle - shearing interferometry , shearography
错位散斑干涉法
Laser speckle interferometry was used as the experimental method to test the coefficient of thermal expansion ( cte ) of the metal composite leads used in the packaging structures and the thermal deformations of the entire packaging structures due to the change of temperature from room - temperature to 150oc
通过实验和数值模拟的方法对其热变形和热应力进行了研究。采用激光散斑干涉法测量了从室温到150oc的封装用金属复合引线的热膨胀系数和整个封装结构的热变形。
So knowing the distributing law of the strain field and how the strain field changes with the actuator ' s size is necessary in this text , electronic speckle pattern interferometry is used to test different strain fields produced by bonded actuators with different size . after the fringe is thined , its spine is got . based on the theory of speckle metrology , the displacement from the fringe is got , at last the strain field and how the strain field changes with the actuator ' s size is got
本文用电子散斑干涉法对不同尺寸的粘贴型压电驱动器的诱发应变场进行了实验研究，将所得的干涉条纹进行细化处理，得到干涉条纹的骨脊图，根据散斑干涉计量术的原理对干涉条纹骨脊图进行数值计算，得到诱发应变场的位移图以及粘贴型压电驱动器的尺寸变化对诱发应变场的影响。
