Energy beam position verification
First Claim
1. A computer program product comprising at least one non-transitory computer readable medium having stored thereon computer-readable program code portions, the computer-readable program code portions comprising one or more executable portions configured for:
- providing an energy beam spot having a first focus directed toward at least two locations on a work table,detecting at least two positions of said energy beam spot on said work table created with an energy beam having said first focus,providing said energy beam spot having a second focus directed toward said at least two positions on said work table,detecting at least two corresponding positions of said energy beam spot on said work table created with said energy beam having said second focus,comparing said at least two positions created with said first focus and said at least two corresponding positions created with said second focus, andverifying said position of the energy beam spot by verifying that said at least two positions created with said first focus deviate less than a predetermined distance from said corresponding at least two positions created with said second focus.

Abstract
A method for verifying a position of an energy beam spot, said method comprising the steps of: providing a calibrated energy beam having a first focus in a at least two positions at a work table, detecting said at least two positions of said energy beam spot on said work table created with said energy beam having said first focus, providing said calibrated energy beam having a second focus in said at least two positions at a work table, detecting said at least two positions of said energy beam spot on said work table created with said energy beam having said second focus, comparing said at least two positions created with said first and second focus, wherein said position of the energy beam is verified if said positions created with said first focus are deviating less than a predetermined distance from said positions created with said second focus.

17. A non-transitory computer readable medium having stored thereon a program element configured and arranged when executed on a computer to implement a method for verifying a position of an energy beam spot, said method comprising the steps of:
-
providing an energy beam spot having a first focus directed toward at least two locations on a work table, detecting at least two positions of said energy beam spot on said work table created with an energy beam having said first focus, providing said energy beam spot having a second focus directed toward said at least two positions on said work table, detecting at least two corresponding positions of said energy beam spot on said work table created with said energy beam having said second focus, comparing said at least two positions created with said first focus and said at least two corresponding positions created with said second focus, and verifying said position of the energy beam spot by verifying that said at least two positions created with said first focus deviate less than a predetermined distance from said corresponding at least two positions created with said second focus. - View Dependent Claims (18, 19, 20)
