1. A calibration system for use in calibrating a laser tracker, the system comprising an artifact comprising:
a main segment having opposed first and second ends;
a first segment extending from said first end of said main segment, wherein said first segment is restrained in six degrees of freedom relative to said main segment when said first segment is in a locked configuration;
a first end plate coupled to said first end of said main segment, said first end plate defining first and second receiving apertures;
a first protruding member extending from said proximal end of said first segment, said first protruding member of said first segment being configured to be received by said first receiving aperture of said first end plate when said artifact is in a deployed configuration; and
a second protruding member extending from said proximal end of said first segment, said second protruding member of said first segment being configured to be received by said second receiving aperture of said first end plate when said artifact is in the deployed configuration.
