相位不连续点对自适应光学的影响
Effect of branch points on adaptive optics
-
摘要: 分析了激光在湍流大气中传输时，若光束波前中出现相位不连续点，自适应光学校正能力降低的原因，通过数值模拟计算了当光束波前中出现相位不连续点时对自适应光学校正的影响，表明在传输过程中出现不连续点的情况下，为了提高自适应光学的校正能力，必须要考虑不连续相位的影响。Abstract: The reason for the degradation of adaptive optics system for atmospheric turbulence compensation when branch points are present in phase is analyzed in this paper. The influence of branch points in phase on adaptive optics system is numerically calculated. The result shows that the ability of adaptive optics system can be improved by taking into account the phase discontinuities when branch points are present in light propagation.
