    "abstract": "In this paper, we report high-precision absolute distance and vibration\nmeasurements performed with frequency scanned interferometry using a pair of\nsingle-mode optical fibers. Absolute distance was determined by counting the\ninterference fringes produced while scanning the laser frequency. A\nhigh-finesse Fabry-Perot interferometer(F-P) was used to determine frequency\nchanges during scanning. Two multiple-distance-measurement analysis techniques\nwere developed to improve distance precision and to extract the amplitude and\nfrequency of vibrations. Under laboratory conditions, measurement precision of\n$\\sim$ 50 nm was achieved for absolute distances ranging from 0.1 meters to 0.7\nmeters by using the first multiple-distance-measurement technique. The second\nanalysis technique has the capability to measure vibration frequencies ranging\nfrom 0.1 Hz to 100 Hz with amplitude as small as a few nanometers, without a\npriori knowledge.",
