Abstract
A method of reducing jitter error in a laser scanning system adapted to produce a scanned image including a number of lines of an object. The method includes the steps of providing a reference object arranged such that the scanned image produced by the laser scanning system includes a reference image of the reference object, processing the reference image to calculate an error arising from non-repeatable displacement of the lines of the reference image, and adjusting at least one operating parameter of the laser scanning system in response to the calculated error.

A method of reducing jitter error in a laser scanning system adapted to produce a scanned image of an object, the scan comprising a number of lines, the method comprising the steps of:
- providing a reference object such that the scanned image produced by the laser scanning system includes a reference image of the reference object;
- processing the reference image to calculate an error arising in the laser scanning system;
- and
- adjusting at least one operating parameter of the laser scanning system in response to the calculated error;
- wherein the reference object is periodic in the direction of the line of scan of the laser scanning system.
