Abstract
This paper extends the application of a novel wavelet-based periodic error compensation algorithm in fiber-coupled heterodyne interferometry. In this case, the amplitudes of periodic error may be fluctuating and traditional digital algorithms are not well-suited. The wavelet-based method, however, has the ability to compensate non-stationary periodic error. In this work, the algorithm is used to compensate periodic error in simulated and experimental constant and experimental non-constant velocity motions and to reduce the error by approximately 80.1%, 81.2% and 68.3%.
