反射式双F-P干涉仪光纤位移传感器的理论分析

THE THEORETICAL ANALYSIS OF THE OPTICAL FIBER DISPLACEMENT SENSOR WITH REFLECTIVE DUAL F-PINTERFEROMETERS

提出了一种反射式双F-P干涉仪光纤位移传感器方案,在这个方案中采用LED作为光源。根据部分相干光的干涉理论对该方案进行了理论分析。

A scheme Of optical fiber displacement sensor with renective dual F-P interferometers is presented.In this scheme a LED is used as light source. The scheme is analyzed theoreticalJy according to the interfefence theory of partially coherent light.
