长度计量技术是研究长度测量,保证量值准确和测量单位统一的技术。在古代,人类为了测量田地等就已经进行长度测量,随着光栅、磁栅、感应同步器、激光等新技术的出现,一些测量范围大、分辨率高的新仪器也产生了。本文阐述了长度计量技术的相关原理和测量基础、意义和任务,介绍了常用的长度计量技术。
Length measurement technology is the length of the study to ensure that the accuracy of measurement units and the unity of technology. In ancient times, mankind had already measured the length of fields for measuring fields. With the advent of new technologies such as gratings, magnetic grids, inductosyn, and lasers, some new instruments with large measuring ranges and high resolution also emerged. This article describes the principle of length measurement technology and measurement basis, meaning and tasks, introduces the commonly used length measurement technology.
