The invention discloses a super-formation lens array and method for correcting non-uniformity of an infrared detector. The super-formation lens array is etched at a lower surface layer of a substrate,and each detector in the infrared detector array and each super-formation lens in the super-formation lens array are same in size. The method comprises the steps of (1) performing radiation measurement on the detector; (2) scanning a digital-to-analogue image; (3) acquiring super-formation lens focus corresponding to each sampling point; (4) designing the super-formation lens; and (5) generatingthe super-formation lens array. By the super-formation lens array, the volume of an infrared imaging system can be reduced, the super-formation lens array has the advantages of lightness and integration, the non-uniformity correctness during the infrared imaging process can be effectively performed, the infrared imaging quality is improved, and the super-formation lens array has the characteristics of wide application range and high real-time property.
