Claim 7:
8. The method of claim 3, comprising at least one of:
guiding the first energy beam to the first determination region with a first beam guiding unit defining a portion of the first irradiation unit, and determining the first parameter of the first calibration pattern with the first calibration pattern located at the first position of the first determination region, and determining the calibration status of the first irradiation unit based at least in part on the image data comprising the first calibration pattern generated by the second on-axis determination unit; and/or
guiding the second energy beam to the second determination region with a second beam guiding unit defining a portion of the second irradiation unit, and determining the second parameter of the second calibration pattern with the second calibration pattern located at the second position of the second determination region, and determining the calibration status of the second irradiation unit based at least in part on the image data comprising the second calibration pattern generated by the first on-axis determination unit.
