    Recently, the yaw sensor would need to be developed their accuracies and repeatability. This research presents the design of a couple single beam laser (CSL) technique for residual error reduction of tape measuring development project. The result of comparison method of CSL and yaw module with laboratory's angular interferometer are satisfactory, and the deviation of measurement error is within and less than 0.1%.

    Yaw error measurements using a new designed yaw sensor were carried out to determine the characteristics of yaw errors and analyze the behavior of the structural guide. Laser interferometers have generally been used in calibration laboratories for the angular measurement of measuring tape calibration systems, and their performance must be verified to determine whether it meets the laboratory specifications. The yaw sensor technique is identical to the error compensation used in a measuring tape calibration, and also has some special parameters. Although the yaw error observation period is very short, it is sufficiently accurate for a carriage yaw sensor. The results of a yaw error measurement comparison between a yaw sensor and the angular measurement system of a laser interferometer were satisfactory. The measurement uncertainty of a yaw sensor calibration was approximately U = 40 arcsec at a confidence level of 95%.
