Paper Abstract

We have proposed a novel wavelength scanning fiber-optic interferometer for absolute distance measurement. Based on the digital signal processing techniques, an algorithm to effectively discriminate phase information, eliminate perturbations and overcome the random sway of the scanning, is established. So that the practical demands of precision 0.05 micrometers and resolution 0.01 micrometers can be satisfied.
