| 摘要 |
A fiber-optic sensor head is disclosed for an optical current or magnetic-field sensor which can have an optical fiber which includes a magnetooptically active sensor fiber which is optically connected to at least one polarization-defining element. The sensor fiber can be arranged in a magnetic field to be measured or around a conductor carrying current to be measured and can be in the form of a coil, with the coil defining a coil plane (A) with a surface normal (N<SUB>s</SUB>), and with the at least one polarization-defining element having a marked axis (f). The sensor head can be flexible in the area of the sensor fiber, and an adjustment means can be provided for adjustment of a predeterminable angle beta between the marked axis,(f) and the surface normal (N<SUB>s</SUB>) or for adjustment of predeterminable angles beta, beta' between the marked axes (f) and the surface normal (N<SUB>s</SUB>).
