Title:
OPTICAL FIBER MAGNETO-OPTICAL DETECTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2010/075809
Kind Code:
A1
Abstract:
An optical fiber magneto-optical detecting device comprises a light-guiding input part (10) used for importing polarized light; a Faraday magneto-optical rotator (2) which is a magneto-optical crystal and used for affecting the intensity of the polarized light along the change of a magnetic field; a light-guiding output part (30) used for exporting the polarized light; and a compensation unit (1a, 1b) used for rotating the imported polarized light, thus avoiding near-zero desensitization, and compensating the temperature error of the magneto-optical crystal. The compensating unit (1a, 1b) is provided between the light-guiding input part (10) and the Faraday magneto-optical rotator (2) or between the Faraday magneto-optical rotator (2) and the light-guiding output part (30).
