A simple and novel method for simultaneously measuring two-dimensional rotation angles of the linear guide track was presented which is based on a single-mode fiber-coupled laser module.The measuring model was established by adopting laser collimation technique.The system includes a fixing part and a moving part.The measuring principle of yaw and pitch was analyzed.The error separation is realized in theory.The experiments of stability,repeatability and its comparison with the double-frequency laser interference measuring system have been carried out.The practical results of the experiments show a good consistence with theoretical analysis.The systemic resolutions of measuring angles are better than 0.5".
