Abstract (in Japanese) (See Japanese page) 
(in English) We constructed the Fabry-Perot interferometer using a Physical Contact polished ferrule endface attached to single-mode fiber facing to a metal mirror. This interferometer with a DFB-LD light source detected reflected power waveform were sinusoidal due to interference according to displacement of gap between a ferrule and a mirror. At the continuous measurement of movement of mirror, we could detect double phase of reflected power due to the waveform modulation of the ferrule continuously moved on gap. We tried to modulate the interference wave a ferrule position modulation other than a sensor part. As a result, it was confirmed that interference waves with phase difference could be obtained.
