Abstract

In this paper, a new measuring system is proposed which can measure the 3D position and orientation of rigid bodies. Its measurement principle is based on detection of laser beam reflected from a specially fabricated mirror that looks like a triangular pyramid having an equilateral cross-sectional shape. The mirror has three lateral reflective surfaces inclined 45 degree(s) to its bottom surface. We call this mirror 3-facet mirror. The 3-facet mirror is mounted on the object whose position and orientation are to be measured. The measurement is operated by a laser-based optical system composed of a 3-facet mirror, a He-Ne laser source, three position-sensitive detectors.
