Abstract: |
A 2-D concentric lens rotor used as tracking reflector in the laser tracking interference measurement system or optical triangular tracking measurement system is composed of reflector with semi-spherical structure and a drive rod passing through center of two forks, and two motors arranged at 90 deg to each other and with semi-circular drive fork on each motor axle. Its advantages include easy position regualtion, no inertial load, simple structure, and high measuring precision. |
