| Zusammenfassung: | A polarization scrambler based on fiber wave plates is disclosed. A λ/4 unit is connected between a first polarization control unit and a second polarization control unit through single-mode fibers; a first motor of the first polarization control unit and a second motor of the second polarization control unit simultaneously forwardly and reversely swing in the range of +/−90°, such that polarization states in the system constantly change, for achieving the purpose of polarization disturbance. The polarization scrambler based on fiber wave plates provided by the present invention has low loss, good effect, low cost and simple structure, and is convenient for manufacturing. Its speed is up to milliseconds to meet demands of most optical fiber sensing systems and optical fiber communicating systems. |
