Fiber-optic sensors for measurements of torsion, twist and rotationBudinski, Vedran (Avtor) Đonlagić, Denis (Avtor) fiber optic sensorstwist sensorsrotation sensorscircular birefringencelinear birefringenceFBGpolarizationoptical fibersFiber Bragg GratingsOptical measurement of mechanical parameters is gaining significant commercial interest in different industry sectors. Torsion, twist and rotation are among the very frequently measured mechanical parameters. Recently, twist/torsion/rotation sensors have become a topic of intense fiber-optic sensor research. Various sensing concepts have been reported. Many of those have different properties and performances, and many of them still need to be proven in out-of-the laboratory use. This paper provides an overview of basic approaches and a review of current state-of-the-art in fiber optic sensors for measurements of torsion, twist and/or rotation.20172017-06-22 10:32:15Znanstveno delo66365ISSN: 1424-8220UDK: 681.586.5:620.175OceCobissID: 10176278COBISS_ID: 20282902DOI: 10.3390/s17030443ISSN pri članku: 1424-8220NUK URN: URN:SI:UM:DK:TQNYWEZ4sl
