| 摘 要： | 在比较了各种光纤测速仪的特点之后,提出了一种基于激光束反射原理,一路发射多路接收的全光纤测速系统,并详细介绍了系统的原理和结构.由于采用多根光纤回路及准直透镜,本系统不仅可以获得良好的出射光束,还可以将漫反射信号通过透镜会聚到后焦面的多根接收光纤中,从而扩大了接收口径,增强了接收光强.实验与理论分析表明,该系统具有较大的测速范围,稳定性好,可以对远距离运动目标进行有效测速.

| Abstract: | Based on beam reflectance, an all-fiber velocity measurement system with one fiber emitting and multiple fibers receiving is presented. The principle and structure of this system are introduced in detail. With multiple fibers receiving and collimating lens, the fine collimating beam is not only obtained, but can be converge to the receiving multiple fibers, as a result, the receiving caliber of the system is increased and signal power is enhanced. The experimental result and thoretical analysis show that the system can efficiently measure distant mobile object with high dynamic range and well stability. |
