Abstract
A stabilized fiber-optic interferometer was developed for vibration measurement by using two laser diodes of different wavelengths and one polarization-maintaining fiber. Passive signal processing of two signals in quadrature is used to obtain the vibration amplitude with a resolution of approximately 0.1 nm. An extension of the signal-processing scheme is proposed that provides compensation for bending or temperature-induced transmission losses of the two propagation modes of the fiber.
