Claim:
1. A method for determining a closed trajectory curve ( 10 ) by a laser ( 12 ) and a laser light sensor ( 14 ) having a flat field of view ( 16 ), wherein the field of view ( wherein the method comprises the following steps: A) Rotationally fixed linking of the laser ( B) Rotationally fixed linking of the field of view ( C) Alignment of the laser ( D) Rotation of the first or second shaft ( E) Recording of the X coordinates and Y coordinates of at least three positions of the laser light spot ( F) Determination of the temporally first recorded X coordinate and the temporally first recorded Y coordinate and assignment of a predetermined value of the angle of rotation to the temporally first recorded X coordinate and to the temporally first recorded Y coordinate; G) Determination of the closed trajectory curve ( wherein, in step (G), a plot of the trajectory curve (
