▎ 摘  要

NOVELTY - The system has a controller (2) connected with a laser (1) for controlling output parameter of the laser. Two vibration mirrors (4) are arranged with each other to primarily reflect laser beam in same horizontal plane along two directions. A computer (7) is connected with a control card (6) that is connected with two vibration mirrors. The computer transmits a signal to the control card for controlling the control card to control deflection of two vibration mirrors. The laser emits laser beam to pass through a beam expander (3). Two vibration mirrors secondarily reflect laser beam for entering a tele-centric scanning area lens (5) to project on a polyimide film (9). USE - Laser direct writing based patterned porous graphene preparation system. ADVANTAGE - The system can quickly and accurately prepare high-quality porous graphene, and has better anti-aberration ability and high processing capability, and increases precision of focusing capability. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of a laser direct writing based patterned porous graphene preparation system.
