Paper Abstract

Interferometric displacement sensor based on a two-wavelength interferometry is proposed and demonstrated. A combination of time-shared two-wavelength laser diode and sinusoidal phase-modulating interferometry enables us to realize accurate and wide-range displacement measurement with a simple optical setup.
