| Abstract: | For the purpose of real-time position inspection of components with large curved metallic surfaces by using a flat flexible eddy current sensor array,the measurement technology is investigated and the testing method based on time division multiplexing(TDM) technology is introduced for the eddy current array.The sensing probe and testing circuits of the sensor system are well designed to make the system circuits simpler and reduce the cross-talk of the array elements.Experiments prove that the performance of the sensor system is improved,and it can realize the rapid and high accuracy measurement of the eddy current sensor array. |
