【摘要】 本文在全息光弹性与散班干涉法的基础上,把两者结合起来,提出了散班全息光弹性干涉法。这种方法可同时得到独立的等差线和等和线条纹图,且方法简便,不需要附加光学元件。本文除了给出此方法的光路和实验方法外,还把此方法应用于一个工程实际问题中,获得满意的结果。该方法也适用于全息动光弹性的条纹分离问题。更多还原

【Abstract】 A mothod of combining speckle interferometry with Holophotoelasticity for stress analysis is presenteod.By means of this method the isochromatic and isopachic fringes can be separated if a suitable diffusing plate is chosen, without any addition of optical elements or particular preparation of the specimen. The value of intensity of the interfering light reaching the hologram plate is established and hence the equations of the recorder isopachic fringe patteins are given. This method has been used success-fully for the study of engineering problems. The piesent method is also suitable for fringe separation in dynamic problems.更多还原
