On the basis of a design idea integrated with optical
mechanics and electrinics
this paper presents the techniques of a fine scanning mirror assembly with high resolution for space optics remote sensors. Firstly
the driving scheme of the system is discussed according to the configuration of a camera
and the step motor is chosen as a core of the control system. Then
three parts of mirror assemblies: integrated driving module
fine shafting and SiC pointing mirror subassembly are introduced. Furthermore
the accuracy of the pointing mirror assembly is tested. According to the test results
the angle precision of is better than 40
the precision relative angle rate (rms error) is under 7% at the working speed and the main shafting radial run-out error is 2 m. The results prove that the pointing mirror assembly satisfies all the requirements of the optical remote sensor.
