Abstract
The ISO 53471/1-1995 proposition of the new international standard of vibration pick-up calibration is examined theoretically and experimentally. Regression analysis method is applied for data transforming and error evaluation in sine-approximation method (SAM) for the calibration of vibration pick-ups by laser interferometry. To make a more valuable comparison of this modified SAM with other techniques, i.e. fringe counting method (FCM) and minimum point method, the resolution of the measuring system is increased by using double optical path difference homodyne interferometer. Additionally the uncertainty of FCM is suppressed by implementing the procedure of fringe phase analysis in the turn points of the vibration cycle. Theoretical analysis and the exemplary experimental results for all applied methods are given. The expanded measurement uncertainties about 0.2% of acceleration measurement and about 0.5% of sensitivity measurement (with a 99% confidence level) have been obtained.
