Analysis of Error Sources for Acousto-Optic Displacement Sensors

Abstract

The work is devoted to the analysis of sources of error of displacement sensors, to use the data obtained in the design of new devices, to determine the parameters of future sensors in their design. The paper considers modern designs of displacement sensors with an acousto-optic transducer, briefly examines the principle of operation of sensors with an indication of structural diagrams. The main sources of error of displacement sensors with an acousto-optic transducer are determined. The analysis of each type of sources, their influence on the measurement error of displacement is carried out, analytical expressions are constructed to determine the magnitude of the error, graphs of the dependence of changes in the parameters of the measuring system on the change in the value of the influencing factor are presented.
