A study on the sync guidance of the multi-lasers with the micro-vision

In the application of the multi-beam laser accumulation for high energy, it is a key technology to guide the lasers into a micro area precisely and quickly. This paper proposes a laser spot identify and laser track sync control method, with the micro-vision feedback, parameterizing the laser spot based on the spot's counter characteristics. At the same time, the method is optimized in identifying the mass center and distinguishing the overlapped areas for the laser spots. The distributed method is verified by simulation and experiments. Compared with existing method, the sync control one guides lasers as the same precision but is 4 time higher efficiency under a 4 beam lasers experimental result.
