In this paper, we have introduced the structure and operation principle of CCD Transducer System in the measurement yarndiameter. The test Circuit and Microcomputer COntrol is given.
The result show that video microscopy is more convenient, shortcut and accurate than microscopy and projection. It is suitable for measuring yarndiameter in small fabric sample analysis.
结果表明,视频显微镜法比后两者较为方便和快捷,精确度高,并适合小块布样分析中对纱的细度测定。
