A statistical analysis of the effect of measurement errors on the determination of small vector displacements of diffusely reflecting objects by holographic interferometry is reported. There are two sources of error: inaccurate measurement of fringe-order number and inaccurate measurement of illumination and observation directions. Standard deviations of errors in measured displacements due to these two sources are presented in graphical form for a variety of holographic system geometries. Absolute fringe orders should be measured whenever possible, because fringe readout by scanning leads to very large errors.
报道了对测量误差对通过全息干涉术确定漫反射物体小矢量位移的影响的统计分析。误差有两个来源：条纹级数测量不准确以及照明和观察方向测量不准确。对于各种全息系统几何结构，以图形形式给出了由这两个来源导致的测量位移误差的标准偏差。只要有可能，就应测量绝对条纹级数，因为通过扫描读取条纹会导致非常大的误差。
