Abstract: PROBLEM TO BE SOLVED: To provide an optical fiber multi-layered coil with which acoustic, vibratory, and rotational components can be measured with high sensitivity. SOLUTION: The optical fiber multi-layered coil is constituted by spirally winding an optical fiber F in two or more layers, bonding the layers with an adhesive 7a, and exposing the optical fiber F on the bottom surface and top surface to the outside. The coil is multi-layered and an external force is applied directly to the optical fiber F, so acoustic, vibratory, and rotational components can be measured with high sensitivity.

Abstract: PROBLEM TO BE SOLVED: To provide a heat-resistant optical fiber extremely superior in heat resistance.
SOLUTION: On the outer circumferential surface of a quartz- or glass-made optical fiber (1) composed of a core (1a) and a clad (1d), there is applied a silica microporous body solution synthesized by the sol-gel method from silicon alkoxide, active alcohol for promoting hydrolysis reaction, and a mixed liquid of alcohol and water, with the surface baked to form a silica microporous body film (2) having silicon as the main component. Then, the outer circumference of the silica microporous body film (2) is coated with an organic metallic liquid or an organic metallic paste and baked to form a metallic film (3); thus, a heat resistant optical fiber (100) is manufactured. As a result, extremely high heat resistance is obtained, enabling the fiber to be used under a high temperature environment such as rock near magma of a volcano.

Abstract: PROBLEM TO BE SOLVED: To provide an optical fiber coil for enhancing vibration detection sensitivity.
SOLUTION: Polyimide resin-coated optical fiber 11-1 made by forming a polyimide resin coat 2-1 on an outer circumferential surface of optical fiber 1 is wound into a vortical shape, and the vortical shape is stabilized with a polyimide resin adhesive 3-1. Since the resin coat 2-1 of the optical fiber 11-1 and the resin adhesive 3-1 are made of the same polyimide resin material, vibration imposed thereon from the exterior is inhibited from being reflected or absorbed by an interface between the resin coat 2-1 and the resin adhesive 3-1, and vibration detection sensitivity can be enhanced.
