摘要：
An algorithm for signal processing of long-range fiber optic displacement sensor is described in this paper. The algorithm analyses two signals provided by a measurement system which contains two Fiber Optic Probes (FOPs) placed in front of micro fabricated gold coated silicon grating and determines the displacement of the mobile part online. The algorithm provides a scheme of switching between the two signals from the two probes in their respective high sensitivity zone, without interrupting the displacement measurement. An approach is adapted in order to achieve millimetric range with nanometric resolution which also prevents the noise effects on the measurement making the algorithm reliable.
