| Abstract: | A novel optical fiber acoustic emission sensor is described. Which is following properties: reasonable scheme, a few of low-noise, low drift operational, a 6-pole Buterworth filter and computer as the signal processor. Its resolution was as high A°-level(10 -10 m),bandwidth is from 100 kHz to 1.4 MHz and on-line measurement to be possible. |
