- Example Sentences:
| 1. | The phase and the frequency of the laser light inside the arms will shift in opposite directions
当两管臂内的光束与另一参考光束重叠在一起的时候，它们就无法同步振? ，而会产生摇摆的干涉节拍。 | | 2. | This method doesn ’ t need beam deflection device and can change the reference beam incidence angle with mechanical movement platform only . and the accuracy of system is not getting lower
这种方法不需要光束偏转器件,只需要机械运动平台,仅通过平台的移动,就可以实现参考光束入射角度的变化,而且寻址的精确性并未降低。 | | 3. | 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。 | | 4. | 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。 |
