摘要
空间光学遥感器的光学元件的光学参数通常是根据设计经验来选定的。建立了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。从工程的实际条件出发,当阻尼比为0.03、质量比为0.2时,通过MATLAB编程对光学元件的动态响应进行了数值分析。结果表明,为了尽可能地降低光学元件的动态响应,应该选择合理的动态频率,而不是一味地提高光学元件组件的动态频率。
The optical parameters of optical components for a space optical remote sensor are usually determined by the experience of a designer. By establishing a full damping dynamic analysis model for a space optical remote sensor, the expressions of dynamic response of optical components are obtained. In view of the actual engineering condition, the dynamic response of the optical components is analyzed numerically through MATLAB programming when a damp ratio is 0.03 and a mass ratio is 0.2. The result shows that to keep the dynamic response of an optical component as low as possible, a reasonable frequency should be selected rather than increasing the dynamic response of the optical component subassembly blindly.
