    Aim

    ing at the wide-field-of-view and high-resolution imaging requirements of the airborne photoelectric imaging systems, we design a multi-scale wide-field-of-view and high-resolution optical imaging system based on a concentric spherical lens. The optical system includes a large-scale concentric spherical lens and a small-scale secondary camera array, and it has the advantage of compact structure. According to the spherical aberration and chromatic aberration of the concentric spherical lens, in combination with the small-scale cameras, the aberration is further corrected for the segmentation of the field of view, achieving wide-field-of-view and high-resolution imaging. Furthermore, the whole system is subjected to experiments under stress and at high and low temperatures. The experimental results show that the imaging system has good stability. Besides, the value of modulation transfer function in the full field of view is always close to the diffraction limit of the system, and the square root of the speckle radius is smaller than the pixel size of the detector, indicating good imaging effect of the system. In conclusion, the traditional airborne imaging system cannot satisfy both wide-field-of-view and high resolution at the same time, and provides a new idea for optical imaging system design.
