We present a novel scheme for compensation of transmission loss variations in Faraday effect-based fibre optic magnetic field sensors. Light is sent through the sensing element in opposite directions to form the two signal channels needed for the com

The design and performance of a multimode fiber optic magnetic field sensor utilizing the Faraday effect in an epitaxially grown thick (YbTbBi)IG film is reported. The sensor is found to be linear over a range of more than 100 dB.

Due to their intrinsically favourable behaviour with respect to electromagnetic interference and galvanic isolation, fibre optic sensors are good candidates for current and magnetic field measurements in high power electric transmission systems. Sens

Design and performance of an extrinsic guided wave fiber optic magnetic field sensor is reported. The sensor utilizes a substituted YIG (yttrium iron garnet, Y3Fe5O12) thin film as the waveguiding sensing element. A polarization maintaining fiber dow

Magneto-optical garnet materials such as YIG, undoped as well as substituted, exhibit a large Faraday rotation. This fact makes them potentially suitable as sensing elements in fibre optic magnetic field sensor systems. We describe both an intensity

As a part of a fibre optical sensor development project we have made an evaluation of different optical waveguiding techniques to study the properties of thin magnetooptical films. Because of the application the methods are focused on the determinati

This paper presents a method for measuring the birefringence in magneto-optical waveguides. A holographic grating on the waveguide surface is used to couple light to and from the waveguide. Since no mechanical contact is necessary for the light coupl
