Therefore, the permanent magnet can be subjected to different magnetic forces through the changed electromagnetic field. By acting on the permanent magnet with different magnetic forces, the high-frequency change in the height of the glass photoreceptor is achieved, so that the glass photoreceptor can form the image output by the projector at different heights, thereby achieving the formation of a three-dimensional image.
