美国国家标准与技术研究院(NIST)物理测量实验室(PML)半导体和长度测量部的测量服务项目,专注于几微米至一米的测量,实现长度量值传递,提供促进美国创新、工业竞争力的测量、标准和基础的技术服务。NIST维护和开发先进的干涉系统,用于将基于频率的SI长度单位复现传递到实物上。推动三坐标机的技术发展、开发用来定量评价三坐标机特性的方法,通过引领和参与活动,对于国际和国内长度计量提供积极支持。
National Institute of Standards and Technology (NIST) Physical Measurement Laboratory (PML) Semiconductor and Length Measurement Division of the measurement services, focusing on a few microns to one meter measurements, to achieve the length of the value of delivery, to promote the United States innovation, industrial competition Force measurement, standards and basic technical services. NIST maintains and develops state-of-the-art interferometry systems for the recurrence of frequency-based SI length units to physical objects. Promote the technological development of CMMs and develop methods for quantitatively evaluating the characteristics of CMMs. By leading and participating in activities, they provide active support for international and domestic length measurement.
