摘要	In order to meet the design requirements of the optical system of a three-line array airborne mapping camera with large field-of-view, high resolution, low distortion, and high environmental adaptability, the structural design of a new optical system was developed. First, according to the overall requirements and the characteristics of stable platform installation, a single-lens technical solution was determined. Then, various parameters of the optical system were analyzed and calculated; the Lagrange Helmholtz invariant of the optical system reached 9.5. Then, the structural parameters of the non-telecentric, telecentric, and semi-telecentric optical system light paths were analyzed and compared. Finally, the structure of a complex semi-symmetrical double-Gaussian optical system with good airborne environment adaptability was designed. The designed optical system has good imaging quality. The full field-of-view modulation transfer function is better than 0.36 at a Nyquist frequency of 100 lp/mm in the VIS-spectrum and better than 0.6 at a Nyquist frequency of 50 lp/mm in the RGB-spectrum. The maximum relative distortion of the full field-of-view of the optical system is better than 0.1%. In the uniform temperature range of 0 to 40, the full field-of-view modulation transfer function is better than 0.3. The test results of the laboratory gradient resolution board show that the static resolution of the camera reaches 102 lp/mm. The flight verification test results show that the camera photography resolution reaches 0.16 m at 2 km. The design completely satisfies the requirements of environmental adaptability and resolution of the large field-of-view three-line array airborne mapping camera. 2018, Science Press.
