使用激光束产生的干涉条纹能在生产速率下无物理接触地连续测量出扭绞线的外径。使用这种技术的系统已经成功地用在铝绝缘线流水生产线上。
The interference fringes produced using the laser beam can continuously measure the outer diameter of the twisted pair without physical contact at the production rate. Systems using this technology have been successfully used in aluminum-insulated wire-line production lines.
