A new type of semiconductor ring laser gyroscope is introduced, which combines the advantages of simple structure scheme and low cost of fiber optic gyroscope of traditional He Ne laser gyroscope. The accuracy of the gyroscope is analyzed theoretically, and the relationship between the parameters and the parameters of the gyroscope is presented. The processing methods of signal readout and steering discrimination are also proposed. Finally, from the perspective of integrated optics, the design structure of the monolithic semiconductor laser gyro is given. Theoretical calculations show that when the diameter of the passive ring waveguide cavity is 40 mm, the accuracy of the monolithic integrated optical semiconductor laser gyro can reach 0 .0 32 rad / s.
