Abstract:In this paper,the least square deconvolution algorithm is deduced from the orthogonal projection method in Hilbert space.The solution is the optimum one in the sense of least square.Using this method,the dynamic deflection signal is successfully obtained from the signal of inertial transducer,which is distorted seriously.The comparison with other methods proves the effectiveness of this method.This method provides a new approach for the measurement of dynamic deflection of bridge.
Keywords:least square deconvolution algorithm  orthonormal projection  measurement of dynamic deflection
