title = "Improved measurement accuracy based on adaptive Kalman filter",
abstract = "As a ultra-precise measurement apparatus, the heterodyne laser interferometer has been widely used in various industrial fields. However the nonlinearity caused by the nonorthogonality and the ellipticity of two-frequency input sources leads to imperfect displacement measurements. In this paper, the iterated adaptive fading Kalman filter algorithm is used to compensate the nonlinearity error. It can reduce the linearization error by repeated taylor series expansion around our new estimate and obtain high convergence rate. To demonstrate effectiveness of the proposed algorithm, the simulation results are presented with the improved measurement accuracy.",
