Abstract
A novel curved compound eye imaging system is put forward in this paper. Non-uniform hexagonal lens array is arranged on the inner surface of a plano-concave substrate. Based on the geometrical optics, the parameters of each microlens are set according to the position of the lens, and even orders of aspheric lens are used to correct some primary aberrations. Optical parameters of this configuration are entered into numerical ray-tracing simulations (ZEMAX). The result shows that the new curved compound eye can enlarge the field of view (FOV) approximately 50% compared to the lateral compound eye, and the FOV can be up to 150°. The principles and functions of all parts of system are described in detail. At last, the feasibility of ultra-precision machining is studied in this paper.
