摘要
介绍一种微功耗敏感探头的原理以及光纤耦合光动力工作的方法。采用500m长的光纤传输LD（激光二极管）光功率，其出纤功率达3mW，可使小于100μW功耗的探头稳定可靠工作。
The principle of micro-power consumptive sensing probe and the methoud for optically powering probe with optical fiber are described. The LDI's power is transmitted through 500m optical fiber. The output power of optical fiber is 3mW, and the probe with Power consumption less than 100μW has high stability and reliability.
