Absolute Distance Measurement Using Frequency-Scanning Interferometry Based on Hilbert Phase Subdivision
In order to eliminate the influence of laser frequency nonlinearity, the frequency-scanning interferometry (FSI) often uses the beat signal of an auxiliary interferometer as the external clock. The time points at every amplitude peaks and bottoms of the auxiliary beat signal are selected as the samp...
