actuating a laser tracker to emit laser beams on the high-frequency test object and on retrotargets disposed on one or more reflectors; and
measuring the high-frequency test object and the one or more reflectors in terms of their propagation of high-frequency signals using the laser beams incident on the high-frequency test object and on the retrotargets disposed on the one or more reflectors.
8. The method according to claim 7 , further comprising:
calculating correction values based on the laser tracker measurements for aligning the high-frequency test object using a best-fit transformation program, and
outputting the calculated correction values.
