摘要
On the basis of optically powered sensor principles,this paper introduces a practical scheme of an optically powered force sensor using a piezoelectric crystal worlding in close-loop resonant mode.A 3 mW LD stabilized is used as optical source.The optical powering distance reaches 500 m while the total power consumption of the micro power measuring head is only 0.275 mW.The key technical problems of the sensors are presented as well as experimental results.
