In this paper, we present a new method to correct dynamic error (DE) in on-line gamma ray thickness measurement, which significantly improves measurement precision over traditional method, in most cases, by one order of magnitude. Theoretical analysis of DE is presented and the correction method is proposed. In order to further prove our theory, Monte Carlo simulation is taken and the performance improvement is given. The method has been successfully applied to our thickness measurement system and brought dramatic improvement to its dynamic precision.
在本文中，我们提出了一种校正在线伽马射线厚度测量中动态误差（DE）的新方法，在大多数情况下，该方法比传统方法显著提高了测量精度，提高了一个数量级。文中给出了动态误差的理论分析并提出了校正方法。为了进一步证明我们的理论，进行了蒙特卡洛模拟并给出了性能提升情况。该方法已成功应用于我们的厚度测量系统，并使其动态精度得到了显著提高。
