Abstract

The optical error of a cat's eye retro-reflector is a major factor which affects the measuring accuracy of a laser tracking 3D coordinates measuring system based on multi-beam principle. A measuring apparatus is constructed with a Talyrond roundness tester and a HP laser interferometer to measure the optical error of a cat's eye retro-reflector CER75. In the process of measured data processing, non-linearity fitting arithmetic including 2D interpolation arithmetic is used to obtain the optical error in different directions and to eliminate the measuring error. Experiment results indicate that the maximum optical error of a cat's eye retro-reflector is about 4μm. After error correction, 3D coordinates measuring accuracy of the laser tracking system have been improved to some extent.
