| Abstract: | A novel fast steering mirror was designed on the basis of the research on the structure and working principle of a laser autocollimator.The two-dimensional running of the fast steering mirror could be realized by two beeline motors driving two wedges.Self-locking of the wedge mechanism could be used to achieve precision and accuracy.The work scope of the fast steering mirror was A±6.975＇,E±5.25＇.When the laser autocollimator was working,the laser could always return the CCD.In order to ensure the precision less than 1″,the angle of the wedge was 4°,and the step length of the motor was 0.001 5 μm.The experiment results showed that the precision was less than 1″. |
