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.
