摘　　要：叙述了一个浮法工艺玻璃厚度的在线测量装置。系统由Mach-Zehnder干涉仪、讯号处理单元和微处理机组成。介绍了测量原理,讨论了由机械振动、电磁干扰和温度引伏所引起的误差,以及减少这些误差的方法。最后给出并比较了在某生产线上用该系统和千分尺分别得到的数据。结果表明精度约1％。An apparatus used for measuring thickness of plate glass on a production line using floating technology is described. The system consists of a Mach-Zehnder interferometer, a signal processing unit and e. micro processor. The principles of measurement are presented. Errors stemed from mechanical vibration, e,m. and te mperature disturbance and methods for deducing these errors have been discussed. Finally, some deta obtained from a production line both by the system and a micrometer have been listed and compared. The results show a accuracy of about 1%.
