噪声在“光电微弱信号检测”课程中的应用

Applications of Noise in Optoelectric Weak Signal Detection Course

对于噪声中存在的微弱信号检测,需要采用专门的方法和仪器来抑制噪声。通过在课堂教学中有意识地介绍如何利用噪声来提取微弱信号,对丰富课堂教学内容,培养研究生正确的思维方法和创新意识起到了良好的作用。本文介绍了噪声在激光陀螺与开环光纤陀螺信号处理中的成功应用。

Noise is usually harmful for detection of weak signal in noise and needs to be suppressed with special method and instruments.Examples of using noise for detection of weak signal are introduced consciously in classroom teaching,which enrich teaching content and are useful for cultivating students philosophical thinking and innovative consciousness.Applications of noise in ring laser gyro and fiber optic gyro are introduced in the article.
