一、前言在造纸工业中通常采用橡皮辊驱动机构,以便确保纸张幅面的最佳传递。滚筒的平衡运转对获得良好的功能来说是极重要的。为了能更好地研究滚筒的振动状况,需要寻找一种非接触式测量系统。电容和电感测量接收器由于有很厚的橡皮层而不宜采用,这一难题可以通过 CCD 阵列用光学方法来解决。滚筒从后面加以照明。用一适当的物镜把 First, the foreword In the paper industry usually use rubber roller drive mechanism, in order to ensure the best delivery of the paper format. The balance of the drum is very important for good function. In order to better study the vibration of the drum, need to find a non-contact measurement system. Capacitance and inductance measurement receiver due to a thick rubber layer and should not be used, this problem can be solved by CCD array using optical methods. The drum is illuminated from behind. Use an appropriate objective lens
