英文摘要	Both the dynamic range and the sensitivity are very important parameters of the interferometric fiber-optic gyroscopes (I-FOGs), and generally the large dynamic range and the high sensitivity are contradictory in the open-loop I-FOGs. In this article, an efficient and easy to be implemented signal processing scheme is proposed for enlarging the dynamic range of the open-loop I-FOGs without reducing the sensitivity. A prototype was developed to verify the feasibility of the new scheme and compare its performance with the conventional open-loop I-FOGs. Experimental results show that, compared with the conventional open-loop I-FOG with the same fiber coil and optical devices, the dynamic range of the open-loop I-FOG with the aid of the new signal processing scheme is enlarged to +/- 360 (degrees/s) exceeding the single value area +/- 63 (degrees/s) of the conventional open-loop I-FOG obviously and the bias drift reduces from 0.068 degrees/h to 0.046 degrees/h.
