【摘要】 反射式光强调制型光纤传感技术由于具有其独特的优点,所以在位移检测中得到较为广泛的应用,成为当前国内外的一个研究热点。由于光源的稳定性、外界环境光的干扰以及被测表面反射率的变化严重的影响了其商品化的进程,因此当前的问题是探索性价比更适合产业化的技术方案,使光纤传感技术能更广泛地为国防和国民经济建设服务。介绍了反射式光强调制型光纤传感器的工作原理、最新的研究进展及其在位移检测中的应用。更多还原

【Abstract】 For its unique merits, the reflective intensity-modulated fiber-optic sensing technique was widely applied in displacement detection and became research hotspot. However, the stability of light source, the disturbance of environment and the reflectivity variation of the measured surface had effects on the merchandising process. The current work for us to do was to find out some technique scheme suitable for the product merchandising. Thus the fiber-optic sensing technique could be used more widely in national defence and economic construction. The working principle of reflective intensity-modulated fiber optic sensor was presented. And the latest research findings and the application of it in displacement detection were also given.更多还原
