HIGHLIGHTS
- who: Luming Song and colleagues from the School of Optoelectronic and Communication Engineering, Xiamen University of Technology have published the research work: Phase Unwrapping and Frequency Points Subdivision of the Frequency Sweeping Interferometry Based Absolute Ranging System, in the Journal: Sensors 2022, 22, 2904. of /2022/
- what: In this manuscript, the authors propose an FSI ranging method based on Hilbert transform and Chirp-z transform, which can realize the phase subdivision, the increase in resampled points, and the refinement of frequency points.
- how: The experiments are carried out in a constant temperature and . . .
