We investigate intersubband Rabi flopping in modulation-doped semiconductor quantum wells with and without the propagation effects, respectively. It is shown that propagation effects have a larger impact on Rabi flopping than the nonlinearities rooted from electron-electron interactions in multiple quantum wells. By using ultrashort \pi pulses, an almost complete population inversion exists if the propagation effects are not considered; while no complete population inversion occurs in the presence of propagation effects. Furthermore, the magnitude of the impact of propagation effects may be controlled by varying the carrier density.

提出了一种基于恒幅零自相关(CAZAC)序列的定时同步算法。该算法的CAZAC训练序列由4部分构成,分为6个定时窗口,利用序列的共轭对称和偶对称特性进行相关运算,通过6个窗口相乘得到定时度量函数。仿真结果表明,利用所提算法可获得具有唯一脉冲状峰值的定时度量函数曲线,消除了定时平台以及旁瓣干扰。同时,在信噪比和色散较大的变化范围内,所提算法仍具有较好的定时稳定性。

由于工艺水平的限制,相机靶面不可避免地存在位置安装误差和指向安装误差,为了消除靶面安装误差的影响,定性分析了靶面安装误差;理论推导出显式包含指向安装误差的误差模型及成像模型;得到综合考虑靶面指向安装误差和镜头畸变的全像差模型;利用标定结果对实际像点进行修正。仿真和半实物实验验证了模型和标定方法的正确性,比较得知全像差模型相对于传统像差模型对实际像点有更好的修正效果。
