Abstract

In this paper, we outline a preliminary implementation of primary calibration for a laser vibrometer (LV) on the basis of newly proposed first ISO draft (ISO16063-41). Under some different measurement conditions, primary calibration is preliminarily carried out for investigating dominant uncertainty source. From these results, the effects of acceleration amplitude stability, parasitic motion, measurement position, and spot diameter of measuring beam have been discussed. Some conditions required for achieving reliable calibration is clarified on the basis of the discussion. The strict regulation in the new ISO draft would be almost valid.
