 note = {A phase-shifting Sagnac interferometer that uses wavelength tunability of the laser diode is proposed. A Sagnac interferometer itself is robust for the mechanical disturbances because it has a common path configuration and requires no special reference. Unbalanced optical path introduced between p- and s-polarized beams enables us to implement easy phase-shift by the direct current modulation. Several experimental results indicate that the proposed system is useful for the disturbance-free precise measurement., Advanced materials and devices for sensing and imaging 3 : 12-14 November 2007 : Beijing, China.},
