Signal processing of the optical fiber impulse sensor acceleration

Abstract

Introduction. Feature of the pulsed fiber-optic sensor is a mutual influence of the components of the acceleration vector measured. When processing the signals of the pulse sensor should provide adequate correction value counts for correct measurement results. Main part. It consists of four sections. The first section outlines the method of determining the undistorted values of horizontal components of the acceleration vector acting on the sensor, in the absence of the vertical component of the acceleration vector. The second section outlines the method of determining the undistorted value of vertical component of the acceleration vector. Based on the results obtained in the first two chapters, the third chapter described a method of determining undistorted measured quantities of all components of the acceleration vector. In the fourth chapter provides a quantitative assessment of the effectiveness of the proposed information processing in the case of precision measurements of acceleration. Conclusions. It is pointed to the principal possibility of determining the undistorted values of samples of the vector acceleration components along all axes of sensitivity of the pulse sensor. The method of determination is proposed and a general algorithm is formulated for measuring randomly oriented components of the acceleration vector. It is evaluated the efficiency of correction of pulse sensor signals for example acceler-ometer of micro-accelerations.
