为了使光学元件的动态响应变得尽可能小并满足质量指标,需要对空间光学遥感器的 质量进行分配。通过建立空间光学遥感器的全阻尼动态分析模型,得到了光学元件动态响应的表达 式。根据该表达式讨论了不同动力学系统的动态放大特点。然后从实际工程条件出发,通过MATLAB 编程进行了数值分析,讨论了使光学元件响应尽量小的质量分配条件。结果表明,当阻尼比均为0.03、 频率比β为1.3、质量比为0.51时,光学元件的动态响应接近最小值。本文依据理论公式提出的这种方法 可通过图形判读结果,因此具有结果可靠、简单便捷等特点。

在高精度光纤频标传递过程中,需要对光纤链路引入的相位波动进行测量和补偿,其中引入的频率串扰是影响频标传递性能因素之一。为评估频率串扰对光纤频标传递性能影响,建立了频率串扰对频率传递稳定度的影响模型。在光纤链路温度变化条件下,通过仿真分析和实验研究了频率串扰与稳定度损失之间的关系。结果表明,频标的稳定度损失与串扰因子和频率有关。串扰因子越大,信号的阿伦方差曲线整体上移幅度越大,且串扰因子和稳定度损失峰值近似呈线性关系;频标频率变化时,频标传递的长期稳定度并非只受由温度缓慢变化引起的时延缓慢漂移的影响,也与频
