Design and mechanism analysis of a novel type compact single mirror laser scanner

A novel type of laser scanner employing a permanent magnetic suspension and spherical hinges has been developed. It consists of a single mirror based on linear electromagnetic actuators. This system has design features of playing the role of a two-dimensional tilt actuator by means of driving the electromagnetic actuators, and it provides good mechanical characteristics such as low distortion and damping, high optical angular deflection, and high dynamical performance (more than 1 kHz). This paper describes the configuration of the device and presents experimental results to demonstrate its performance and effectiveness.
