自由空间传播的光学模式受到像差的严重影响，例如由大气湍流引起的像差。这些光学畸变是由于沿着光路温度和压力变化引起的光密度变化引起的。这些畸变不仅随时间变化，而且沿着整个光路变化。这种像差导致体光学湍流，无法使用单平面光学校正进行校正。我们提出了一种方法，使用一个7面多光转换器，可以纠正光学像差所产生的1 km的光路高达D/r 0 =20和小于-9dB的11个空间模式的组合串扰。
Free-space propagating optical modes are acutely affected by aberrations such as those caused by atmospheric turbulence. These optical distortions are due to variations in optical density that arise from changes in temperature and pressure along an optical path. These distortions don’t only change in time, but along the entire optical path. Such aberrations results in bulk optical turbulence that cannot be readily corrected using single plane optical correction. We present an approach, using a 7 plane multiple light converter that can correct optical aberrations arising from 1km optical paths with up to a D/r0=20 and with less than -9dB combined crosstalk for 11 spatial modes.
