A fibre optic displacement sensor
1982 (English)In: Acta IMEKO, Budapest: Akadémiai Kiadó , 1982, 51-60 p.Conference paper (Refereed)
Fibre optics is beginning to find use for sensing purposes. Fibre optic sensors have many interesting features, e.g., their immunity to interference from electromagnetic fields. The paper briefly discusses different sensor principles. A displacement sensor using multimode, step index fibres is desccribed. Measurement data showing a resolution of 0.05 nm/sqrt(Hz) in a 150 Âµm linear range is given. In this sensor, the light coupling between two fibre ends varies with the position of a movable mirror. A mathematical model of the sensor is presented. Application to pressure sensing is also discussed.
