Mathematical Functions of a 2-D Scanner with Oscillating Elements
The bi-dimensional (2-D) scanners are used in a variety of applications, e.g. marking, cutting, and welding, in art applications, not to mention security and military applications. The 2-D scanners were developed using different combinations of uni-dimensional (1-D) scanners [1,2]: polygonal [3,4], or galvanometric .
Our present approach refers to a 2-D scanner consisting of two 1-D galvoscan-ners, of a type we previously developed  in order to obtain an enhanced duty cycle with regard to the state-of-the-art [6,7], which means a higher efficiency in using the available time for the scanning process. The main advantage of this 2-D system is the fast, precise positioning of the laser beam reflected by each of the mirrors of the two individually driven scanners in any point of the two axis of the scanned plane.
