ENHANCED DEPTH OF FIELD BASED ON UNIFORM RELATIVE ILLUMINATION VIA LENS WITH LARGE DISTORTION |
摘要 |
A lens system is provided that comprises an enhanced depth of field based on a uniform or near uniform relative illumination via a lens with a large distortion. The distortion can be corrected with image processing equipment. The lens system can comprise an aperture stop and a group of lens, wherein there can be about five lenses in the group of lenses. The lens system is designed for relative illumination such that the light distribution over the lens system is substantially uniform.
