散斑场 meaning in English

speckle field
specklefield

We can obtain the sequence of speckle interferograms by continuously recording the temporal speckle interference field caused by the object temporal deforming using the imaging system
通过摄像系统连续地采集这一时变散斑场，可获得一系列时间序列散斑干涉图。
The diffraction formula and statistical law of optical fields are used to get the cross - correlation function of intensities of laser speckles of the moved diffuse object
该方法利用光传播的菲涅尔衍射公式和光场的统计规律，给出散斑场光强在散射体位移前后的高斯光束相关函数的表达式。
The extracted height - height correlation function and the random surface parameters obtained ever since conform with those obtained by the measurement of afm in chaper 3 , based on the light scattering theory of kirchoff approximation , we propose the method for the extraction of surfaces parameters from the correlation functions of speckles intensity produced by light scattering in the region near the random surfaces
我们以对三个高斯相关的随机表面样品的实验测量为例，对该方法行了验证。所测得的结果与用原子力显微镜测量的结果符合得很好。第三章根据基尔霍夫近似下的光散射理论，提出了从随机表面附近衍射区内的散斑场相关函数中提取随机表面参量的方法。
