| 摘要 |
The invention relates to a method and arrangement for measuring a magnetic field with the aid of the Farraday effect, wherein a first and second linear- polar light signal (L1 or. L2) passes through a magnetic field sensitive measuring section (2) exhibiting the Farraday effect in an opposite direction. A first or second analyzer (14 or 12) for the first or second light signal (L1 or. L2) is arranged downstream from the measuring section (2). The first and second analyzer angle ( psi 1 or psi 2) of the first or second analyzer (14 or 12) and first or second polarisation angle ( PHI 1 or PHI 2) of the first or second light signal (L1 or. L2) injected into the measuring section(2) are adjusted to the intrinsic axes (x,y) of linear birefringence in such a way that an error occurring as a result of the temperature dependency of the linear birefringence for a given Faraday angle ( rho ) different from zero is minimized.
