We present a new technique for measuring the squares of the amplitudes and phases of partial vortex-beams in a complex beam array in real time. The technique is based on measuring the high-order intensity moments and analyzing the solutions of a system of linear equations. Calibration measurements have shown that the measurement error at least for a beam array of 10–15 beams does not exceed 4%.

测量涡流束阵列中的涡旋谱，没有波峰的切割和胶合

我们提出了一种新技术，用于实时测量复杂光束阵列中部分涡旋光束的振幅和相位的平方。该技术基于测量高阶强度矩并分析线性方程组的解。校准测量表明，至少对于10–15个光束的光束阵列，测量误差不超过4％。
