Sentence examples for periodic error from inspiring English sources

Periodic error amplitude is varied through independent rotation of a half wave plate and polarizer.

Test results show that the periodic error can be eliminated using the polynomial fitting method.

This paper provides experimental validation of the digital first-order periodic error reduction scheme described by Chu and Ray.

In dynamic measurements, periodic error is usually on the order of nanometers, which impacts the dynamic measurement accuracy.

Due to beam leakage in the interferometer, imperfect polarization components, and ghost reflections, the displacement measurement suffers from periodic error, whose pitch is multiple harmonics of the Doppler frequency.

The measurement validation shows that this approach can effectively eliminate the periodic error for both constant and non-constant velocity motion, and the residual error reaches to the level of the background noise of the interferometer.

Eccentric binaries which are out of phase when comparing two solutions cause large, periodic errors in the velocity.

Periodic errors due to dial turns were corrected for by using data measured in an ERI building and all available data from previous observations.

RC designed to eliminate periodic measurement error is also presented, with results from computer disk drives.

Therefore, a phase lead type iterative learning controller (ILC) is designed and implemented in conjunction with linear feedback and feedforward to reduce this periodic tracking error by more than two orders of magnitude.

Further, the principle of superposition can be employed to analyze the periodic transmission error excitation and/or combined excitation problems provided that the excitation frequencies are sufficiently apart from each other.
