With the development of precise mechanotronics measuring instrument  machining center  CNC machine and various precise location testing technology  a higher request is put forward to the accuracy and the function of raster measurement system. In this article it is concluded that double readheads is the most reasonable configuration scheme through tests of single readhead scheme  two readheads and four readheads.

For example  in the marine environment  shipboard conditions  the instrument has a waterproof  corrosion-resistant  easy maintenance and other functions  while carrier-based optoelectronic devices from a single visible television configure the development of integrated infrared system and ranging system as one of the single-station measurement system  due to the spherical structure has sufficient internal space exactly adapted to this need. In this paper  the horizontal axis of a spherical four-way structure. From aspects of the spherical four-way split in the form and shafting design and finite element analysis of the detailed design. A spherical four-way horizontal axis system  diameter 550mm  weight 19kg sphere  in the 40kg load  the maximum deformation of 3.3m  fully meet the requirements. The shaft of the structure of the shaking is less than 2 arc seconds  the vibration test  the re-examination instrument accuracy change is less than 1 arc seconds. Verify that the structure is stable and reliable. 2012 IEEE.   Grazing exit X-ray fluorescence spectroscopy 期刊论文  OAI收割 HIGH ENERGY PHYSICS AND NUCLEAR PHYSICS-CHINESE EDITION, 2005, 卷号: 29, 页码: #REF! 作者:  Xu Q(徐清);  Wei XJ(魏向军);  Huang YY(黄宇营);  He W(何伟);  Xu, Q 收藏  |  浏览/下载：39/0  |  提交时间：2016/04/12 grazing exit X-ray fluorescence spectroscopy  instrument development  thin film
