Analysis of the Type and Application of Guides for Indoor Standard Devices for Large-scale Length Measurement

This paper introduces the primary type and principles of linear guides and their application in large-scale length measurement. Performance analysis was made on two mainstream types of guide, i.e. the 80-m aerostatic guide at the National Institute of Metrology, China and the 60-m linear motion rolling guide at the National Institute of Measurement and Testing Technology, China, which could shed light on development of standard devices for large-scale length measurement.
