| Abstract: | A signal character for mechanically dithered ring laser gyroscope is introduced simply at first. An applied low-noise, large dynamic range pre-amplifier and compare circuit for signal detection system is designed. The basic operating theory is analyzed and, the transfer function, relative error and noise of the circuit are computed. The theoretical analysis and the experimental results show that the circuit can meet the requirement of ring laser gyroscope. The preamplifier has been successfully applied to the detection system for mechanically dithered ring laser gyroscope and relatively good results has been obtained. |
