Abstract

Due to the optical fiber have a small diameter and it can propagate light efficiently, it is possible to realize ultra-compact remote sensors. We have invented to the fiber-optic pressure sensor utilizes magneto-optical effect with polarized light, ring-type interferometer and a magnetic material, in order to propose the pressure measurement system which can measure in vivo or in harsh environments. We have confirmed that the prototype sensor based on magneto-optical effect was possible to detect pressures in range of −4 to +40 kPa.

利用磁光效应的光纤压力传感器的研制

由于光纤直径小，光的传播效率高，实现超小型遥感器成为可能。我们发明了利用偏振光磁光效应、环形干涉仪和磁性材料的光纤压力传感器，提出了一种可以在体内或恶劣环境下进行压力测量的系统。我们已经证实，基于磁光效应的原型传感器可以检测到−4至+40 kPa范围内的压力。
