<p>The present invention relates generally to optical scanners. The invention has advantageous applications e.g. in the field laser technology, such as coating and machining with cold ablation technology. An optical scanner according to the invention has a rotating mirror (210), and the reflecting surface (214) of the mirror has an angle in relation to the axis of rotation (216), which varies as a function of the position in the mirror. This way it is possible to provide an optical scanner without discontinuation points and an accurate scanning speed throughout the scanning area.</p> |
