| 摘 要： | 提出一种合成孔径激光雷达(SAL)调频激光器带宽测量的新方法。使用法布里-珀罗(F-P)扫描共焦腔,对调频He-Ne激光器的带宽进行测量,结果表明,在测量激光器的调频带宽时不受调频速率的限制,可以实现对SAL系统调频激光器的带宽测量。

| Abstract: | A novel method is proposed to measure the bandwidth of frequency modulated laser in synthetic aperture ladar system.The bandwidth of a FM He-Ne laser is measured effectively by use of Fabry-Perot spherical confocal cavity.The experimental results show that the method can work well when measuring the FM laser with any chirp rate in synthetic aperture ladar system. |
