| 英文摘要 | In order to deter direct sunlight from coming into contact with the light aperture of geostationary optical remote sensor, an in-orbit deployable heat dissipation lens hood was designed, and the optical-thermal characteristics and structural characteristics of the proposed lens hood were analyzed and tested. First, the special thermal environment of geostationary optical remote sensor was analyzed to determine the design requirements of the lens hood. After that, a deployable heat dissipation lens hood with inner diaphragms was designed and a prototype was made. Then, the optical-thermal characteristics of the lens hood were analyzed by ray tracing and heat flux calculation, and the structural characteristics of the lens hood were analyzed through mechanical simulation. Finally, a functional test was carried out on the prototype, and the dynamic stiffness was tested in the compression locked state. The results show that the lens hood can significantly improve the optical-thermal characteristics of the optical system and meet the overall dynamic stiffness requirements. |
