Assignee: BRUNSON INSTRUMENT COMPANY
Field: Measurement (Instruments)
Classification: CPC G  F | IPC F  G

Claim 14:
15. A method of calibrating a laser tracker, the method comprising:
utilizing a first laser target to obtain a first measurement that is associated with a position of a first end of an artifact when the artifact is in a first orientation;
utilizing an alignment mirror and one of the first laser target or a second laser target to obtain a second measurement that is associated with a position of a second end of the artifact when the artifact is in the first orientation;
comparing the second measurement with the first measurement so as to determine a first reference length of the artifact;
utilizing the alignment mirror to obtain the first measurement;
obtaining a third measurement that is associated with the position of the first end of the artifact;
obtaining a fourth measurement that is associated with the position of the second end of the artifact;
comparing the fourth measurement with the second measurement so as to determine a first measured length of the artifact; and
comparing the first reference length of the artifact with the first measured length of the artifact,
wherein the third and fourth measurements are obtained without utilizing the alignment mirror.
