摘要
激光多普勒测速(LaserDopplerVelocimetry)以其高精度、使用方便而在速度测试领域得到广泛的应用。人们也因此而忽视了对影响其测试精度的因素进行系统的分析。为此,本文主要对影响激光多普勒测速精度的因素作了具体分析。主要分析了有限渡越时间、测控体中的示踪粒子、光电探测器、激光束定位等因素,并提出了在具体实验时的注意事项。
This paper reviews the formation technology of a new fiber compound fiber Bragg gratings, compares the advantages/disadvamages of some techniques; analysis many prospects of application that FBG will be used in fiber communication and fiber sensors. The summary demonstrates that FBG will make important influence on the whole field of fiber technology.
