  • Device for measuring rectilinear motion
    Patent number: 4847511
    Abstract: Disclosed is a rectilinear motion measuring device which measures the X- and Y-axis displacement errors by detecting displacements of a rectilinearly moving body, while measuring the pitching and yawing errors by detecting the angle of inclination of the moving body and measuring the rolling error by detecting the displacement of the moving body at two different positions. For these purposes, the rectilinear motion measuring device is provided with means for detecting the displacement of the light source of a luminous flux generating means, means for detecting the displacements of the moving body on a magnified scale of .times.2n, and means for detecting the angle of inclination of the rectilinearly moving body.
