We describe in detail a calibration method for the terminal voltage of small accelerators used for ion beam analysis, with the elastic resonance of 16 O(α,α) 16 O at 3038keV as the intrinsic measurement standard. The beam energy relative to this resonance is determined with a precision around 300eV and an evaluated reproducibility of 1.0keV. We show that this method is both robust...
Two-way satellite time and frequency transfer (TWSTFT) is the technique which allows time scale comparisons at the nanosecond level. Until now, this uncertainty level is restricted to those institutes which both can exchange signals through the same single transponder of one telecommunication satellite. Only in this case the calibration scheme of circulating a portable TWSTFT reference station is...
Error propagation for camera model and the impact of the number of image points on the errors of image coordinates are investigated. The camera calibration process is performed using Mathlab toolbox. The error propagation equations are derived by taking the appropriate partial derivatives with respect to various measurement errors for image coordinates. Our experiment results show that the error propagation...
