Abstract
An optical position sensor of aircraft comprises light emitting means, first optical wave guiding means connected at its one end to the light emitting means, and polarizing means connected at its one end directly to the other end of the first optical wave guiding means. A Faraday effect element is connected at its one end directly to the other end of the polarizing means and has reflecting means at its other end. A movable magnetic scale is disposed in opposed relationship to the reflecting means and having a plurality of magnetized segments mounted thereon. The sensor further comprises polarization detecting means connected at its one end directly to the other end of the Faraday effect element, second optical wave guiding means connected at its one end directly to the other end of the polarization detecting means and adapted for guiding the light from the polarization detecting means, and optoelectric converting means connected to the other end of the second optical wave guiding means.
