A design method for artificial compound eye with large Field of View (FOV) is presented, where the lens array are arranged on curved surface. By researching the FOV characteristic of each lens and studying the FOV relationship between each lens and the whole system, an optimized design method was presented. The design method of single lens was also described and the arrangement criterion was also given. The imaging structure designed by using the criterion can not only realize the detection with no dead field but also use the least lenses. Experiments were carried out and the imaging performance of the artificial compound eye designed was verified.
