【発明の名称】機械的力を測定するブラッグ格子装置、ブラッグ格子装置の使用法、およびブラッグ格子装置を駆動する方法
Document Type and Number:
Japanese Patent JP2002538426
Kind Code:
A
Abstract:
The invention relates to a Bragg grating device for measuring a mechanical force (K, K'), comprising an optical fiber (1) and a Bragg grating (11) formed in said optical fiber, in addition to a force transmitting device (2) that converts the force to be measured into a force (K1, K1') that expands and/or contracts the fiber (1). The device (2) provides higher measuring sensitivity and sensors for measuring other physical variables such as electric tension, temperature, acceleration, vibration, etc. with higher measuring sensitivity.
