例句与用法
- this device splits the light beam into a measuring light beam and a reference light beam .
此设计把光束分成测量光束和参化光束。 - be different with other botdr systems, the coherent self-heterodyne botdr system uses only one consecutive laser . the light from consecutive laser is divided into two beams, the detecting light and the reference light, by a coupler
与其他的botdr系统分别使用两台激光器不同,自相干外差的布里渊散射分布式光纤传感系统采用一台激光器,经耦合器分为两路光束??探测光和参考光束。 - at the same time, it uses a frequency translator to obtain a frequency shift, which is equal to the brillouin frequency in fiber . then the detecting pulsed light and the cw reference light can coherent . this method greatly improved the system ’ s sensitive and signal to noise ratio ( snr )
同时在探测光路中引入一个光移频环路,使探测光移频后再经光纤中布里渊频移,其后向布里渊散射光频率与参考光束大致相当,可进行相干自外差探测,大大提高了系统的探测灵敏度以及系统的信噪比。
