- 数字全息和计算程式 计算全息图的制作和再现过程主要分为以下几个步骤: 1抽样。得到物体或波面在离散样点上的值。 2.计算。计算物光波在全息平面上的光场分布。 3.编码。把全息平面上光波的复振幅分布编码成全息图的透过率变化。 4.成图。在计算机控制下,将全息图的透过率变化在成图设备上成图。如果成图设备分辨率不够,再经光学缩版得到实用的全息图。 5.再现。这—步骤在本质上与光学全息图的再现没有区别。 -Digital Holography and CGH fo

- 在理论分析的基础上,着重采用Fox-Li数值迭代法计算了平平腔振荡模式的振幅分布和相位分布。计算结果表明,在经过300 次渡越后,归一化的振幅分布和相位分布实际上已不再发生变化,镜面中心处振幅最大,从中心到边缘振幅逐渐降落,镜面已不再是等相位面了。但对于菲涅尔数较大的平行平面腔,特别是在镜面中心及其附近,平面波是很好的近似,只有在镜的边缘处,波前才发生弯曲。则已找到光腔的一个自再现模式或横模分布。另一方面,分析了腔镜倾斜扰动对平平强腔内振荡模式的影响。数值计算表明,腔镜倾斜破坏了场分布的对称性,
