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. The sine approximation method is applied to our calibration system. Under some different measurement conditions, primary calibration is preliminarily carried out for achieving reliable measurements. From these results, the effects of acceleration amplitude stability, mechanical distortion, position of measuring beam, and spot diameter of measuring beam have been discussed. Some conditions required for achieving the reliable calibration is indicated on the basis of the discussion. Additionally, the strict regulations of the distance between spots and such amount of mechanical distortion would be indispensable for guaranteeing a higher reliability of such calibration within an expanded uncertainty (k = 2) of less than 0.5 %.
