散射光数字全息检测过程的统计光学讨论

Statistical Optics Discussion of Measurement for Scattering Light Digital Holography

从统计光学及标量衍射的基本理论出发,研究散射光数字全息重构波面与原散射波的关系,提出非平滑物体双曝光全息过程中散射光传播及干涉的简化模型.基于简化模型及计算机数值计算,对一个双曝光全息干涉系统转动形变的检测过程进行了理论模拟,并通过与该系统实验测量的比较,证实了简化模型的可行性.

In order to solve the difficulty in explaining the scattered light＇s interference question using the theory of the change of smooth wave front＇s optical distance directly, based on scalar diffraction elementary theory and statistical optics, the relationship of wave front reconstruction of scattered light digital holography and original scattered light are studied, and the simplification model of scattered light＇s propagation and interference in the process of double exposure holographic interference late peoposed. Using this model and numerical calculation of computers, the theory simulation is carried on to a rotation deformation examination process of the system of double exposure holographic interference. Through comparing with this system＇s experiment survey,it is confirmed that the simplification model is feasible.
