Abstract
A sensor which exploits dual-interferometric technique for absolute displacement measurement is proposed. The interferometer performing the measurement task operates low coherent-optical interferometry and highly coherent-optical interferometry simultaneously. The absolute measurement range, which is determined by the bandwidth of the Bragg wavelength reflected by the Fiber Bragg Grating (FBG) in the sensor, is larger than 6mm. And the measurement resolution, which is determined by the highly coherent-optical interferometry, is less than 1nm.
