Dynamic Error Analysis of the Thickness Measurement Using γ Ray

文中证明了采用γ射线透射方式对运动物料厚度进行在线测量时存在动态测量误差。并通过对误差贡献参量的分析与仿真 。

This paper has proved that there is a dynamic error result from the variation of thickness with time on on-line thickness calibration by radiation transmission. Decreasing measurement time-interval could reduce the error effectively. But the statistic error will increase when we shorten the measurement time-interval. It also gives some measures, which can be taken in the practice to minimize the error.
