提出了一种非接触式轧辊磨损在线检测的方法。研究了轧辊磨损量在线检测的原理及方案，利用激光自混合干涉位移传感器进行多点测量，将轧辊磨损量转化为微位移量进行检测，从而得到磨损量。信号处理中基于相位展开原理进行自混合干涉相位提取，重建外腔物体运动信息，并利用插值法降低了辊身振动和随机噪声的影响，提高了系统测量分辨率与精度。实验结果表明，该方法的测量分辨力可达到几十微米。

A method of non-contact on-line measurement for testing roller wears based on the measuring principle of laser self-mixing interference was put forward. The principle and project of roller wear testing is investigated. A self-mixing interference displacement detector was used for multi-point measurement and translating the roll wear quantity into micro displacement to get the wearing capacity of the roll. In signal processing,the phase unwrapping method is used to extract phase and the interpolation method is used to improve the test resolution and accuracy. The result of the experiment shows that the resolution of this measuring method is refined to micron.
