Abstract

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.
