High-precision Absolute Distance Measurement using Frequency Scanned Interferometry
In this letter, we report high-precision absolute differential distance measurements performed with frequency scanned interferometry (FSI). Absolute differential distance was determined by counting the interference fringes produced while scanning the laser frequency. A high-finesse Fabry-Perot interferometer was used to determine frequency changes during scanning. Two new multi-distance-measure...
متن کاملHigh-precision absolute distance measurement using dual-laser frequency scanned interferometry under realistic conditions
In this paper, we report on new high-precision absolute distance measurements performed with frequency scanned interferometry using a pair of single-mode optical fibers. Absolute distances were determined by counting the interference fringes produced while scanning the frequencies of the two chopped lasers. High-finesse Fabry–Perot interferometers were used to determine frequency changes during...
متن کاملAbsolute Distance Metrology for Long Distances with Dual Frequency Sweeping Interferometry
− Coherent absolute distance interferometry is one of the most interesting techniques for length metrology. In frequency sweeping interferometry (FSI), measurements are made without ambiguity, by using a synthetic wavelengths resulting from a frequency sweep. Accuracy is mainly dependent on the capability to measure the synthetic wavelength, using a Fabry-Perot interferometer (FP) to count reso...
متن کاملHigh-precision Absolute Distance and Vibration Measurement using Frequency Scanned Interferometry
In this paper, we report high-precision absolute distance and vibration measurements performed simultaneously with frequency scanned interferometry using a pair of single mode optical fibers. Absolute distance was determined by counting the interference fringes produced while scanning the laser frequency. A high-finesse Fabry-Perot interferometer(F-P) was used to determine frequency changes dur...
