Design And Implementation Of A Laser Gyroscope Test System

This paper studies the application of the software and hardware design of integrated test system of laser gyro based and calibration of the inertial instrument error and precision statistics.Firstly, we introduce the basic principle of laser gyro, and carries on the error analysis, pointed out the error influence on the system, the error model of laser gyro is applied in practical engineering. Secondly, this paper discusses the integrated testing system of laser gyro hardware and its working principle, through the system, automatically for laser gyro electrical test and static characteristics. Thirdly, this paper discusses in more mature division calibration method in engineering, and using the principle of the method to calibrate the parameters of the system. Finally, in the form of in-depth study based on the system, the high-speed data acquisition card write efficient application, mainly to complete the design of laser gyro shake digital filter, the standard deviation calculation software of laser gyro, inertial instrument error model processing software and integrated output test software.
