摘要: <正>激光散斑干涉法是继激光全息干涉术之后发展起来的一种精密、简便的光测力学新方法。散斑干涉对于测定粗糙表面的面内位移特别灵敏,故用它来测定木材的抗拉弹性模量。

Abstract: The principle, testing apparatus, preparation of samples, experimental methods and resultes are reported by using laser speckle interferometry for measurement of wood elastic modulus, the issues encountered and the measures taken to improve the measurement accuracy are discussed.
