在干涉图数据处理中,构成波差多项式的基底函数的性质,正则方程的求解方法,抽样点的分布与数量等对确定波差函数的解都有影响;同时在数值化的过程中,不可避免地要引入测量误差,它对波差函数的解也有较大的影响.本文利用数理统计分析的方法对上述问题产生的误差进行精确的定量分析,并给出了各自模拟计算的结果及判断波差多项式的基底函数与项数的选择、抽样点的分布与数量、拟合结果等是否合理的定量判据.

基于二维非定域非线性介质中的库默模型,研究了库默孤子的传输特性。分析发现,存在一群二维库默高斯孤子簇,如环形孤子、项链孤子和半月形孤子。数值模拟表明高斯孤子和环形孤子是稳定的,其他孤子是不稳定的;并且非线性调制系数、调制深度等参数对孤子传播特性有着重要的影响,随着它们的增加,孤子的稳定性增加。

设计并制作了一种硅雪崩光电二极管(APD)四象限探测器芯片, 基于该芯片研制了一款新型高灵敏度制冷型APD四象限探测器组件; 创新性地将探测器芯片、热电制冷器、前置放大电路和增益控制模块集成在带光窗的金属外壳中; 该组件制冷加热速度快, 在-45~70℃环境温度内可使器件恒定工作在10±2℃。测试结果表明, 相对于传统的PIN四象限探测器组件, 由于APD探测器本身能产生雪崩增益, 该组件的灵敏度提高了近两个数量级, 作用距离更远。
