摘　　要：运用弱散射体产生的部分显现散斑场相位差自由标准偏差的近似表达式,分析了双会聚透镜组成的成像系统产生的部分显现高斯散斑场相位差的自由统计分布。By using the general approximate representative of free standard deviation of phase difference for partially developed speckle fields produced by a weak diffuser, the free statistical distributions of phase difference of partially developed Gaussian speckle fields in the image fields for a two-lens imaging system have been analysed.
