Time delay filter technique is applied in the control of reducing residual vibration of a flexible beam.
将时滞滤波器技术应用在柔性机械臂残留振荡的控制中，获得了好的控制效果。

One way to improve beam quality is that the frequency having high nonlinear gain should be filtered by spatial filter pinhole.
改善的方法之一就是利用空间滤波器小孔将非线性增长很快的部分滤掉。
