Abstract
In this study, we propose a laser beam pointing method that allows for simultaneous control of position and angle using two commercially available galvanometer mirrors. Two mirrors are placed next to each other. Mathematical calculations show that the outgoing beam angle for the system is defined by the control angles of the two mirrors, and the one-dimensional position of the outgoing beam is defined by the angles of the two mirrors and the distance between their rotational centers. Using a line laser, two galvanometer mirrors, and a camera, we confirmed that the one-dimensional position and angle can be controlled using the proposed method. This method can be used for dynamic fabrication and manufacturing in future.
