A New Approach to Improve the Performance of Phase Laser Range Finder
Present phase laser range finder system mostly adopts the phase detection methods of fixed optical ruler and constant mixing frequency. However, its phase detection accuracy is comparatively low when the measuring range varies continuously and its operational speed is also slow. Being directed against this situation, the thesis proposes a new phase detection system on the basis of adaptive frequency conversion. The experiments show that the phase detection accuracy of this new system is superior to 1/1000, and the operational speed is twice as before.
