Conference paper


The paper presents the modeling of a galvanometer-based scanning device with an increased duty cycle, i.e. a high efficiency of using the available time for the scanning process. From the basic dynamic equations of the oscillating element, the active torque and the command function that have to be used are derived. An analytical study is performed on the possible profiles of the scanning function, and an optimum solution is demonstrated, in order to obtain an as small as possible inertia torque and an as high as possible duty cycle. The active torque and the command functions are deduced for this optimum scanning law. A MathCAD study of the command function with regard to the desired scanning (oscillating) frequency completes the modeling process.
