摘要:

基于强度矩方法,我们开发并实现了一种多模梯度折射率光纤中实时并行信息传输的新技术。要做到这一点,有必要在厄米-高斯基中测量模式振幅和相位的频谱。同时,测量了信息熵和空间相干度。

英文摘要:

We have developed and implemented a new technique of parallel information transmission through a multimode graded-index fiber in real time based on the approach of intensity moments. To do this, it was necessary to measure the spectrum of the mode amplitudes and phases in the Hermite-Gauss basis. At the same time, informational entropy and the degree of spatial coherence were measured.
