Abstract :
We propose a stroboscopic two-wavelength interferometer that is applicable to displacement measurement of rotating object. The system we propose uses two different wavelengths and two CCD cameras which are equipped with a high-speed electrical shutter. It allows us to measure displacement through the disturbance-free phase measurement.
