【摘要】 本文介绍用散斑摄影术研究相位物体的一种方法。这种方法是基于测量由于散射光通过试验介质产生折射而引起的散斑表观位移。作为应用实例,讨论了测定玻璃厚度不均匀性的原理和方法,并给出了详细的实验描述和计算结果。更多还原

【Abstract】 A method for studying phase objects by speckle photography is presented.It isbased on the measurement of apparent displacement of speckle which is caused by the refractionof diffused light as it passes through the test medium.As a living example,the principle andmethod of quantitative determination of inhomogeneity of glass thickness are discussed.The setupof experiment and results are described in detail.更多还原
