To meet ground resolution of 0.2 m when flying at an altitude of 10000 m,we design a high-resolution CCD aerial photography lens with a long focal length,and catadioptric optical path.In this design,uses ordinary glass to corrected the secondary spectrum of large diameter and long focal length.In conditions of large area array,high resolution CCD as a receiver with a single pixel size,and effective size is 36 mm× 48 mm.The modulation transfer function of every field close to the diffraction limit in 60 lp/mm,and meet the image quality requirements.Final achieve the all-time observation and measurement with wide band range of 470-950 nm.
