Abstract

Time-sharing acquisition of the spectral information in different spectral bands is the premise of the spatial multispectral imaging.In order to meet the requirement of the spectral subdivision in multispectral imaging of a satellite camera, a spectrometer device was designed in this paper.The filter wheel drive mechanism was designed to achieve high precision and high stability cut-in and cut-out optical path through a large diameter angular contact ball bearing peripheral driven by stepper motor.The dynamic characteristics of the mechanism were validated by numerical model and modal test.The effectiveness of the filter wheel for the launch environment was analyzed by swept sine test and random vibration test.The ground micro-vibration test was used to describe the on-orbit stability for the filter wheel.The numerical analysis and experimental results indicate that the filter wheel guarantees both the structural safety and on-orbit stability requirement.This kind of peripheral driven filter wheel with large thin-walled bearings provides a new method for the space application of the large aperture satellite camera.
