Abstract: PURPOSE: A device and a method for measuring motion errors of a linear stage is provided to measure 6 free motion errors of a linear stage in which a super precise operation is needed with a single equipment configuration and to efficiently inspect motion characteristics. CONSTITUTION: A device for measuring motion errors of a linear stage comprises a light emitting device(10), a first beam splitter(14), a first measuring unit(20), a second measuring unit(30), and a third measuring unit(40). The light emitting unit outputs laser beams. The first beam splitter separates the beams output from the light emitting unit. The first measuring unit receives one among the beams separated by the first beam splitter, thereby measuring one-way straight linear motion errors of a linear stage. The second measuring unit measures angular motion errors and the other one-way straight linear motion errors of the linear stage by using the other beams separated from the first beam splitter and diffracted by a diffraction grid. The third measuring unit measures another one-way straight liner motion errors of the linear stage by circular-polarizing the beams refracted by the diffraction grid.
