从系统结构、工作原理、软件功能等方面分析了旋转式光学线材测径系统。该系统在微处理器控制下 ,光学头围绕高速行进中的赤热线材转动 ,将线材直径的阴影成像在固体摄像机的线性CCD图象传感器上 ,通过光电转换 ,获得高精度的线材横截面的冷态 (2 0℃ )尺寸。介绍了该系统的线材横截面图像显示、信息存储、数据分析、自测试和校验等功能。对其提出了进一步改进的设想 ,以增强系统的性能。

The structure,mechanism and software function of a optical rotating bar diameter measurement instrument system (ORBIS) are analyzed. Driven by a microprocessor,an optical head rotates round a fast forward moving red hot bar,and projects the shadow image of the bar's diameter on the liner CCD image sensor.By means of the optical electric translation,the high accurate dimensions of the bar's cross section at the reference temperature(20℃)are obtained.The system has other functions,such as image display of the bar's cross section,information memory,data analysis,self test and calibration and so on.The possible improvements are suggested on further enhancing the performance and function of this instrument.
