Alignment of focus-adjustable off-axis reflective optical system
摘要
Abstract
A space interactive measurement and datum transmission system with high accuracy was proposed,aiming at precise alignment problem of off-axis reflective optical system.Therefore the highly accurate angle location of focusing angle and systemic optical axis was realized.The diameter of the system was 450 mm,and focus-adjustable range was from 0.5 km to infinity.After accurate positioning of focusing angles,only wave aberration of off-axis three-mirror optical system in infinite position needed to be adjusted to satisfy requirements,and the wave aberrations of all focus position in the system could be guaranteed to accord with design requirements,thus improving adjustment efficiency greatly.The experimental results show that the wave aberrations of the system in infinite position,1.5 km,2.5 km and 0.5 km are 0.1λ,0.11λ,0.5km and 0.2λ respectively,which are all better than design requirements.关键词
