摘要
本文提出一种光纤耦合光功率(光推动低功耗)差压敏感探头工作的原理,介绍单根多模光纤传输双波长光功率与测量信号的方法。讨论系统通道的参数选取以及提高测量精度的几点措施。
The paper presents the operation principle of a optically-powered sensor to measur diffeential pressure. Its probe powered by light only comsumes tens micro watt. The optial source fro power and signal can be transmitted to and fro by a single multiple mode optical fiber. The power and signal lights have different wave length. The paper not only introduces how to dsign the system and also how to select its parameters.
