Fiber-Optic Sensors for Measurements of Torsion, Twist and Rotation: A Review †

View Article: PubMed Central - PubMed

ABSTRACT

Optical 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.

Mentions: In [105] an extrinsic fiber optic rotation sensor was presented where a rotatable quarter-wave mirror was positioned in the front of a PM fiber (Figure 25). Relative rotation between the fiber principal axis and the mirror axis was measured by using this fiber-mirror setup as an optical feedback in an active laser system based on a Vertical-Cavity Surface-Emitting Laser (VCSEL). Rotation of the mirror in front of a PM fiber caused the optical powers of two VCSEL polarization modes to change with changing mirror angular position.
