Bragg network extensometer for monitoring works of art, comprises optical fibre which has Bragg networks inscibed within and is covered by a reinforced plastic core also measuring equipment |
摘要 |
The extensometer consists of an optical fibre (4) which has Bragg networks (Rn) formed internally by photoincription and is connected to an optical switch and measurement unit (10,8). A reinforced plastic core (6) is co-extruded around the glass fibre and makes contact with the host material (2). Anchors (An) are firmly connected to the core and placed on either side of each Bragg network
