In the paper the reader can learn information around laser, position errors, laser vector, laser vector measurement, and vector measurement. This paper gives the reader explanation about displacement errors, measurement, laser beam direction, straightness errors, and temperature sensor.
Lots of information like the laser vector, angular errors, the laser beam, errors, and vector measurement technique are explained in this paper. Here are chosen from the paper:
More precisely, the measured linear errors are the vector sum of errors, namely, the displacement errors (paral lel to the linear axis), the vertical straightness errors (perpen dicular to the linear axis), and horizontal straightness errors (perpendicular to the linear axis and the vertical straightness error direction), projected to the direction of the laser beam. Please note that Ex(x), Ey(x), and Ez(x) are the position error components due to all the motion errors including the position error, two straightness errors, three angular errors, and even nonrigid body motion errors.
Even more, this paper contains information regarding laser beam, interferometer, compensation, the vector measurement, and accuracy.
