本文提出一种新的数字散斑计量术——白光数字散斑照像术.它以两维数字偏心滤波技术实现全场信息的表征,而以数字相关技术实现点信息的表征.文中给出了计量方法、理论分析及实验结果.

A new digital speckle metrological technique called white light digital speckle photography is presented. 2-D digital decentric filtering and 2-D digital correlation techniques are suggested to be used to represent the whole field information and point information respectively. The metrologioal method, theoretical analysis and experimental results are described and given in detail.
