| 摘 要： | 激光自混合干涉技术是一种新型测量技术,其具有结构简单、紧凑、易准直等优点,因而广泛应用于振动测量领域.采用压电陶瓷尾纤调制技术,对分布式布拉格反射光纤激光器自混合干涉系统进行调制,最终实现了对外界物体振动信号的重构.重构结果表明,当外界振动物体峰峰值在λ/4到2λ范围时,重构振动信号的峰峰值误差低于0.3%.

| Abstract: | T he laser self‐mixing interference technology is a novel measurement technology , w hich has been widely applied in vibration measurement on account of its distinct advantages of simplicity ,compactness and self‐collimating .In this paper ,the piezoelectric pigtail fiber modulation technology was used to modulate the distributed Bragg reflector fiber laser self‐mixing interference system .Finally ,the reconstruction of external object vibration signal was achieved .The reconstruction results showed that the error of reconstructed vibration signal peak value was less than 0 .3% ,when the external target peak value was in the range of λ/4 to 2λ. |
