Signal Processing Techniques for Wavelength Scanning Interferometry
A novel wavelength scanning fiber optic interferometer for absolute distance measurement has been proposed. Based on the digital signal processing techniques, an algorithm to effectively discriminate phase information, eliminate perturbations and overcome the random drifts of the scanning wavelength, is established. So, the practical demands of a precision 0.05 μm and a resolution 0.01 μm are met.
