Abstract
The invention relates to a method for describing a predetermined desired course (1) with a beam of particles or waves, wherein a movable beam-directing device influences the direction of the beam, so that the latter describes an actual course (3, 4). The deviation of the actual course (3, 4) from the desired course due to inertia is minimized by specifying a corrected desired course (2), which describes diversions at the point of direction changes. The invention also relates to the use of this method for laser structuring or for writing guard plates or dial plates.
Claims10
A method for describing a course in accordance with a desired course having a direction change, comprising using a beam of particles or waves, and a movable beam-directing device which influences the direction of the beam so that it describes an actual course with a velocity VB, when projected onto a surface, further comprising converting the desired course by a drive device, while taking account of a response error time due to the beam-directing device's mechanical inertia in a corrected desired course which, in the vicinity of the direction change from a first direction to a second direction describes a diversion which is obtained by appending and/or deleting arbitrary sections to/from the desired course, and wherein the corrected desired course is translated by the drive device into control instructions for the beam-directing device.
