In this article, we propose a method for improving accuracy in calibrating Leeb hardness testers using fiber interferometric systems. The calibration system is implemented using the photonic Doppler velocimetry technique. This paper provides estimates of the measurement uncertainty arising in the calibration system and describes a method for improving accuracy, which takes into account the signal-to-noise ratio, sampling rate, and processing parameters.

里氏硬度计校准用干涉法的准确性

在本文中，我们提出了一种使用光纤干涉仪系统来提高校准Leeb硬度测试仪的准确性的方法。校准系统是使用光子多普勒测速技术实现的。本文提供了对校准系统中出现的测量不确定度的估计，并描述了一种提高精度的方法，该方法考虑了信噪比，采样率和处理参数。
