摘要：
Optical scanning is established by superimposing the alternating magnetic field of a coil magnet with the permanent field set up by a permanent magnet which surrounds the coil magnet. Both magnets are fixedly secured to a support at one axial end of the magnets and a flexible diaphragm is secured to the other axial end of the permanent magnet. A scanning mirror is effectively attached between the support and the diaphragm. When the coil magnet is activated, the diaphragm is rapidly flexed which causes the movement of the scanning mirror.
