Utilizing the light scattering property of transparent media, holographic interferometry is applied to the measurement of displacement at the interior planes of three dimensional bodies. The use of a double beam illumination and the introduction of a fictitious displacement make it feasible to obtain information corresponding to components of displacement projected on the scattering plane. When the proposed techniques are invoked, it is possible to eliminate the use of a matching index of refraction fluid in many problems involving symmetrically loaded prismatic bodies. Scattered light holographic interferometry is limited in its use to small changes in the index of refraction and to low values of relative retardation. In spite of these restrictions, a large number of technical problems in both statics and dynamics can be solved.
利用透明介质的光散射特性，全息干涉测量法被应用于测量三维物体内部平面的位移。采用双光束照明以及引入虚拟位移，使得获取与投影在散射平面上的位移分量相对应的信息成为可能。当采用所提出的技术时，在许多涉及对称加载棱柱体的问题中，可以避免使用匹配折射率的液体。散射光全息干涉测量法的应用仅限于折射率的小变化和低相对延迟值。尽管有这些限制，但仍可解决大量静力学和动力学方面的技术问题。
