A closed-loop resonator fiber optic gyro (R-FOG) with all digital signal processing is experimentally demonstrated. The closed-loop operation is needed for the R-FOG to achieve high linearity in a wide dynamic range, in which the frequencies of both the clockwise (CW) and the counter clockwise (CCW) lightwaves are maintained at the resonator's resonant frequency. To achieve the closed-loop operation, an additional bipolar digital serrodyne waveform with gentle slope is added to the bipolar digital serrodyne waveform, which serves as a countermeasure against multiple performance degradation factors in the R-FOG. A field programmable gated array (FPGA) based digital processor is developed to realize not only the full operation of the bipolar digital serrodyne waveform but also other signal processing functions for the R-FOG. Measurement results of different rotation speeds show good linearity due to the adoption of the closed-loop operation. |
