5) white light speckle photography
白光散斑照相
1.
The annular aperture white light speckle photography used for measuring deformation and displacement of objects is proposed for the first time.

6) laser speckle photography
激光散斑照相
1.
The displacement field is mesaured by using He-Ne laser speckle photography.
用He-Ne激光散斑照相测量了位移场,通过正交多项式和待定系数法解微分方程,得到了膨胀系数与温度的关系。
2.
A special Laser speckle photography system, by which the heat flux distribution of small objects along their width and height can be measured simultaneously has been developed.
设计了能同时测量小尺寸物体对流换热量沿高度分布和沿宽度分布的激光散斑照相系统,采用以宽度为特征长度的无因次分析,首次得出竖窄条自然对流换热的准则关系,并由实验数据确定了这一准则关系的定量表达式,此关系式还近似适用于块状物体的自然对流换热。
