Magnetic field distribution detection device and method for magnetorheological polishing equipment

The invention relates to the technical field of optical manufacturing, in particular to a magnetic field distribution detection device and method for magnetorheological polishing equipment. A probe of a gauss meter obtains two-dimensional magnetic field distribution of the polishing module in the direction perpendicular to the magnetic induction line of the polishing module under the adjustment of the external moving assembly, and the position coordinates of the external moving assembly, the probe and the polishing module are measured through a line laser measuring instrument; the control unit receives all the position coordinates and the two-dimensional magnetic field distribution, three-dimensional magnetic field distribution of the lowest point of the polishing wheel is obtained through three-dimensional reconstruction, the magnet installation deviation is obtained according to the three-dimensional magnetic field distribution, and then adjustment is conducted. According to the invention, the distribution
