Abstract
Bessel function methods are used on high-frequency vibration calibration. In this paper, a general principle, devices, methods and uncertainty evaluations will be introduced. There are four methods based on Bessel function, which include J0 minimum-point method, J1 minimum-point method, J1 ratio method and J1/J2 ratio method. About this calibration system, the frequency range is 2 ~ 50) kHz and the displacement range is (0.002~0.2) μm. At the same time, two important things will be described, one is a frequency-adjustable piezoelectricity vibrator which is good for high-frequency vibration calibration on account of almost no equilibrium excursion, and the other is double-holes method used in evaluating the linearity of laser interferometer which is important for calibration.
