摘要
分析了自适应望远镜系统的波面补偿剩余误差与频率响应的关系。 分别导出了时间响应误差和波面探测误差与截止频率之间的数学表达式, 表明剩余波差随截止频率的变化规律既有反方向部分, 又有正方向部分, 从而可以找到一个最优频率, 使得系统剩余波差最小。
Abstract
The relationship between residual wavefront phase error and frequency response in an adaptive optical telescope is analyzed. Mathematical formulations are derived for temporal response error and wavefront measurement error respectively. The results show that one part of residual wavefront phase error changes with cut-off frequency proportionally and another part inversely, so it becomes possible to find an optimal frequency which makes the systematic residual wavefront error minimal.
