ccording to the ray optical theory, the imaging properties of optical arrays are analysed. A general imaging transfer matrix is obtained, which includes a special case of paraxial ray approximation. Furthermore, we show that plane arrays imaging is approximating phase conjuation, and it is the phase conjugation only for the paraxial case. Using a new pseudoconjugator-coneshaped corner arrays, the wavefront distortion compensation is demonstrated, and the experimental results are consistent with the theory of this paper.
