IMPACT DETECTION OPTICAL FIBER SENSOR, STRESS CONCENTRATION PLATE, AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide an impact detection optical fiber sensor using a stress concentration plate with a shape which reduces working time. SOLUTION: A long, narrow fiber support 2 is formed by press working or molding. The stress concentration plate 1 is formed with a plurality of holes 3 formed in the longitudinal direction on the fiber support 2. After arranging an optical fiber 6 on the stress concentration plate 1 in the longitudinal direction thereof, the two are molded with a molding member 7. COPYRIGHT: (C)2007,JPO&INPIT
