介绍了一种信号时域压缩的方法,在全光系统中实现光脉冲信号压缩。红光差拍干涉形成的移动干涉条纹等间隔匀速擦除由紫外光差拍干涉形成的移动光腔。通过调整光腔移动速度,实现信号时域上不同程度的压缩。
A method of signal time-domain compression is introduced, and the optical pulse signal is compressed in the all-optical system. The moving interference fringes formed by the red-light beat interference uniformly remove the moving optical cavity formed by the ultraviolet-light beat interference at equal intervals. By adjusting the moving speed of the optical cavity, different degrees of compression in the signal time domain can be achieved.
