COMPARISON OF THE LASER INTERFEROMETRIC SYSTEM OF DYNAMIC FORCE MEASUREMENT WITH THE PTB ACCELERATION STANDARD

摘要

A new interferometric system for dynamic force calibration was developed and investigated. The uncertainty of the system was analyzed by a direct comparison with the acceleration standard measuring devices of the PTB. The comparison includes acceleration measurements using laser vibrometer as well as the calibration of an accelerometer. The results of the comparisons have shown a good accordance of the new interferometric system used in dynamic force measurement with the acceleration standard measurement devices.
