Abstract :
A new technology of realizing the real-time and fast alignment of the pupils and axis between two platforms is presented. The information of optical pupils and axis were detected by the Hartmann sensor. Then a pair of fast tilt-mirrors was controlled with the PI control method. The experiment proves the feasibility and practicability of the technology. The real-time adjustment speed is about the 30 times per second. The optical axis alignment error is 1.2 arc-sec and the pupil alignment error is 0.5 mm. The technology provides a automatic and convenient way for settling the problem of fast optical alignment.
