High-speed Multi-Laser Aiming at Unpredictable Dynamic Targets

We present a method for high-speed multi-laser aiming at unpredictable dynamic targets. By combining high-speed image processing for target detection with galvanometer-based beam steering, the system achieves precise aiming on dynamic targets. Precise alignment of a high-speed camera and mirrors enables robust 2D tracking, supporting scalable and flexible deployment of multiple modules while remaining robust against occlusion. We validated the approach by tracking a sensor-equipped yo-yo and a table tennis ball with RGB lasers, even with a moving module. Potential future applications could include laser processing, information display, free-space optical communication, agriculture, and possibly other fields as well.
