A beam control apparatus consists of an electromagnetic field control component, which has a spherical cavity encircled by a transparent spherical shell, and a beam directing component, which is spherical in shape and located in the spherical cavity. The two components can rotate relative to each other. A clearance between the two components could be filled with lubricant. The beam directing component has a magnetic moment or an electric dipole moment. A controller controls a magnetic field or an electric field in the spherical cavity of the electromagnetic field control component to exert a torque on the beam directing component to control a direction of the beam directing component, thereby controlling a direction of an emergent beam. The present invention is a new terminal technology for free space optical communications, laser scanning, unmanned driving, laser beam driving and location identification.

A near-eye display device is provided, including a display light source, a rotation module and a refractive amplification component. The rotation module rotates around the rotation center axis. The rotation module is provided with a light source scanning component and a mirror group. The light source scanning component converts the light of some pixel points of the display light source into radial propagation, and then the light is emitted through the mirror group and the refractive amplification component. The light source scanning component turns the light of some pixel points of the display light source into radial propagation, so that the optical path becomes radial direction from axial direction, and increases the optical path distance without increasing the volume of the device, which is conducive to reducing the thickness and volume of the device.
