A high degree of cross-correlation of radiation wavefront aberrations, measured from a point reference source and from an extended object (a system of several luminous points), has been for the first time revealed based on simultaneous measurements of phase fluctuations in optical waves propagating in a turbulent atmosphere. The experimental data are consistent with analytical calculations. The high degree of cross-correlation (above 0.97) of measured phase fluctuations proves that an extended incoherent source can be used as a reference source to ensure the operation of an adaptive focusing system.

用点源和非相干发光物体测量的相位波动的互相关

从点参考源和扩展物体（由多个发光点组成的系统）测量的辐射波前像差的高度互相关首次基于对传播的光波中的相位波动的同时测量得到揭示在动荡的气氛中。实验数据与解析计算一致。测量的相位波动的高度互相关（0.97 以上）证明扩展的非相干源可以用作参考源，以确保自适应聚焦系统的运行。
