摘要	To achieve the multispectral imaging of a space optical remote sensor in geostationary orbit, multispectral imaging methods of light filtering in the optical system were investigated. By comparing two kinds of filter modes, the transmissive filter program was selected to switch lights in different bands. Combining the characteristics of the optical system, a scheme was chosen to set a filter wheel mechanism in the vicinity of the focal plane where the degree of light concentration is higher. By comparing the characteristics of different rotating mechanisms, a new type of filter wheel mechanism consisting of a filter wheel assembly and a filter wheel driving mechanism was designed based on a regular five truncated pyramid. The composition and working principle of the mechanism were introduced. Then, the comprehensive performance on filter wheel mechanism was tested before and after the environmental simulation tests. The test results show that the Root Mean Square (RMS) value of filter surface accuracy before and after the tests is better than the average value of /30, the body rotation accuracy is better than 25. Moreover, the mechanism has good self-locking performance and meets the requirements of optical remote sensing multispectral imaging under complex space environments. 2015, Science Press.
