Paper Abstract

In this paper, the 3-D laser Newton-ring device and its application system are introduced. In order to keep the elevator works safely and placidly, One of the key factors is the track of elevator should keep linearity and identical to plumb line. In this paper, a new auto-checking system for the track of elevator that is based on the 3-D Laser Newton-ring device and CCD video is introduced. By using of this system, we can guide the installation or check the track of elevator quickly, automatically and high accurately. Otherwise, the detecting method of 3-D Laser Newton-ring's center is mainly introduced. It is tested that the collimation accuracy is higher than 0.1mm.
