摘    要:本文论证了以散斑照像计量中计量场的系综平均值代表变形信息这样一个基本观点,明确了散斑照像计量中信息的识别是对单一样本计量物所进行的统计识别,进而建立了全场滤波技术中信息分布的统计学模型,并以此解决了测量范围及测量灵敏度等问题。

关 键 词:散斑照像计量  全场滤波  散斑统计

Abstract:In this paper, we show that in speckle photography it is the ensemble average of the metrological field that represents deformation, and that the recognition of information is virtually to estimate the deformation from a single random metrological field. According to the above view points, the statistical distribution model for whole-field information is established and from which the measuring sensitivity and range are derived.
Keywords:Speckle photography  Whole field filter  Speckle statistics
