摘要
PURPOSE: A phase sensitivity determining method and an apparatus thereof are provided to determine the phase delay of an accelerometer by analyzing an interferential signal acquired through a single optical detector.;CONSTITUTION: A beam splitter(400) partitions a laser generated in a laser generator(300). A fixed mirror(500) radiates a reflected first split laser to the beam splitter. An accelerometer(100) radiates a reflected second split laser to the beam splitter. An optical detector measures an interference signal between the first split laser and the second split laser. A phase and magnitude calibrator(1020) measures the phase sensitivity and size sensitivity of the interferential signal transformed to the frequency domain.;COPYRIGHT KIPO 2010
