Abstract

A new scanning laser hear has been designed for measuring up to 6 degrees of freedom at a point. The scanning head is supported by a rotating hallowed shaft, which allows the laser beam to travel up to the scanning head. A set of two mirrors deflects the laser beam with an angle and the rotation of the scanning head produces a conical scan. This work shows that this device can perform a conical scan whose the very small circle scan, before and after the focus point, can measure up to 6 degrees of freedom; the paper focuses on the in-plane rotation. A validation of the novel scanning head is performed. This paper concludes with the presentation of a more compact design for the 6DOF scanning head, which is aimed for complex engineering applications.
