1550nm Faraday Rotator Michelson Interferometer 2X2

1550nm Faraday Rotator Michelson Interferometer 2X2

The Faraday Rotator Mirror (FRM) method is an important solution for suppressing polarization-induced signal fading in interferometric fiber optic sensing systems. In theory, it can completely eliminate polarization fading, but since the rotation angle of the selected FRM is not exactly 45??, residual polarization-induced phase noise will appear in the system. The Faraday Rotator Mirror Michelson interferometer used in the hydrophone can control the difference in length of the two arms to within 1 mm, achieving a low-cost miniaturized desig
