従って、溝周期に測定誤差は生じない。In this shape inspection apparatus, it is assumed that the striated body 2 rotates for some reason during traveling. This rotation equally affects both the turntable 5a and the turntable 5b, and increases or decreases the output of the rotation sensor 6a and the output of the rotation sensor 6b by the same amount, so that no change occurs in the phase difference.
Therefore, no measurement error occurs in the groove period.
