Abstract

Polygon mirror scanners are widely considered to be a vital factor in high-power laser scanners because of their rapid speed and large scanning area. However, one limitation of the polygon mirror design is that back reflection of the laser damages the laser source. This work will perform a detailed analysis of the scanner head, leading to a design that avoids back reflection. This design produces a scan area with a scanning length of up to 305 mm and a width of 6.6 mm. Moreover, the scanning speed can reach 30.5 m/s. Finally, a paint stripping experiment demonstrated the efficacy of the polygon mirror for potential use in commercial applications.
