介绍了一种新型无源无线磁光转速传感器。它是基于测量线偏振光通过正交铁氧体板和分析器传输的强度振荡。板受到圆盘磁场的作用，圆盘的角速度必须测量。由于在orthoterite板的畴壁运动的高速和平滑的可再现的字符，可以连续测量角速度在一个非常宽的范围从超低到MHz的范围。(C)2003 Elsevier B.V.保留所有权利。
A new passive and wireless magneto-optical rotational velocity sensor is described. It is based on measuring the intensity oscillations of linearly polarized light transmitted through an orthoferrite plate and an analyzer. The plate is subjected to the action of the magnetic field of a disc whose angular velocity has to be measured. Thanks to the high velocity and smooth reproducible character of the domain wall motion in the orthoferrite plate, one can continuously measure angular velocities in a very wide range-from ultralow to the MHz range.
