摘要

Based on understanding the working principle of optical fiber sensor, and taking actual concrete project example, and via the optical fiber sensor, the string type instrument and the difference anti-instrument performance comparative analysis, we obtain that each performance index of the optical fiber sensor surpasses the string type and the difference anti-instrument; and it has big measuring range and high, precision specially; compared with the string type and difference anti-instrument, its sensitivity wants the high 1-2 magnitudes, but also can be applied to some special cases; such as in high temperature, strong electronmagetic interference; therefore it is worth applying widely.
