Paper Abstract

The working principle and optical characteristic of cube corner retro-reflector (CCR) using in laser tracking system (LTS) are analyzed. A novel approach has been proposed to determine the effective reflection area of CCR with an arbitrary beam incidence angle. The optical model of CCR under the limitation of maximum incident angle and available reflection area is developed based on rays tracing algorithm. Finally, the relationship between CCR measuring accuracy and beam incident angle is established. Theoretical analysis and experimental results have demonstrated that the CCR measuring accuracy reduces as the incident angle increases, the CCR measuring error is largest when the maximal incident angle is reached. The maximal incident angle at which LTS can still work well is ±35°. The measuring accuracy of a CCR can maintain the manufacturer specifications of LTS only when the incident angle is within ±20°.
