Abstract: The present invention relates to an interferometer and an optical device using same. Unclear interference patterns and restrictions between light source and the interferometer for conventional devices require precise control devices. The present invention enables to control a wave plate of an interferometer to make the amplitude of object beam split by a polarization beam splitter asymmetric against that of reference beam, resulting the brightness of interference patterns adjustable, while using tunable laser as light source of an optical device and adopting frequency scanning methods to prevent restrictions between light source and interferometer. The interferometer and an optical device according to the present invention comprise: a wave plate controlling polarization direction of linearly polarized light incident to a polarization beam splitter; the polarization beam splitter; a wave plate converting polarization beam for the object beam and the reference beam to be interfered in an image pick-up device; and a polarizer.
