7月初，由中国计量院、常州市计量所联合长春理工大学、中航工业青岛前哨<a href="http://opticaltest.oecr.com" target="_blank" class="relatedlink">精密仪器</a>有限公司等多家单位研制的“新型多功能1m<a href="http://laser.oecr.com" target="_blank"

据了解，生活中普通的1米尺就可以满足市民的日常需求，但是在工业领域，<a href="http://b.oecr.com/company" target="_blank" class="relatedlink">企业</a>对这长度的精度要求不断提高。装备制造业是江苏常州及附近地区的传统和优势产业，近年来更朝着“技术含量高、附加值高”的高端装备制造方向发展。这对制造业的“眼睛”——长度几何量<a href="http://opticaltest.oecr.com" target="_blank" class="relatedlink">测量</a>的精度、范围、种类等提出了新的更高要求。</div><div><br></div><div> 为此，中国计量院、常州市计量所牵头，联合长春理工大学、中航工业青岛前哨精密仪器有限公司等多家单位，开展了“新型多功能1m激光比长仪”的研制。旨在为常州、无锡计量技术机构分别搭建一套多功能、可扩展的一维精密测长设备和科研实验平台，提升其对周边地区高端制造业在线纹尺等长度标准器校准以及其它长度几何量精密测量方面的服务能力2016年10月，该装置研制成功。</div><div><br></div><div> <font color="#f00000"><b>该装置实现了线纹尺测量不确定度U=(0.1+0.1L)μm(k=3，L：m)，重复性优于30nm</b></font>，达到了国内先进水平，可以满足目前已有线纹尺的动态高精度校准，有效提升了相关计量技术机构的一维长度精密测量能力水平。</div><div><br></div><div><p style="text-align:
