【摘要】 本文从傍轴波动方程出发,在线性化假设下,导出了任意振幅分布的发射场相位与接收场振幅分布之间的解析关系式,并对高斯光束进行了数值模拟。模拟结果表明,衍射场强度与要求场强度之间符合较好。最后对数值模拟结果进行了讨论。更多还原

【Abstract】 From linearized paraxial wave equation, we derive an analystical relationsbetween the phase on the first DM with arbitrary amplitude distribution and thetarget amplitude distribution on the second DM. Numerical simulations havebeen pevformed and the results demonstrate that the diffraction field intensitycoincides with the required field intensity. Finally the numerical simulatingresults are discussed.更多还原
