描述了相位校正顺序对多共轭自适应光学系统性能的影响。当使用具有不同共轭范围的多个相位调制器时，相位调制器在大气中的共轭图像必须以逆顺序在聚焦后重新成像，并且在该顺序中应用自适应相位校正以实现完美的幅度和相位抵消。在没有中继光学器件的情况下执行校正导致残余振幅和相位像差。它示出，菲涅耳传播的蒙特卡罗模拟，波光学传播的影响变得不可忽略的可见光波长和大的空气质量。
The way in which the sequence of phase correction impinges on performance in multiconjugate adaptive optics systems is described. When multiple phase modulators with different conjugate ranges are used, the conjugate images of the phase modulators in the atmosphere must be reimaged in the reverse order post focus, and adaptive phase correction applied in this sequence for perfect amplitude and phase cancellation. Performing the correction without relay optics results in residual amplitude and phase aberrations. It is shown, by Monte Carlo simulations of Fresnel propagation, that the effects of wave optical propagation become nonnegligible at visible wavelengths and for large air masses.
