摘要： An extended depth of field (EDOF) imaging system (10) is disclosed that has a corresponding extended depth of focus (EDOF'). The imaging system has an optical system (20) consisting of a single lens element (22) and an objectwise aperture stop (AS) arranged substantially at a zero-coma axial position. The single lens element is configured so that the optical system has a select amount of spherical aberration (SA) in the range 0.2λ ≤SA ≤ 2λ, where λ is an imaging wavelength. The imaging system has an image sensor (30) for forming a digitized raw image (IM) of an object (OB). In applications, the raw image can be used directly. The imaging system also has an image processing unit (54) adapted to process the raw images to form contrast-enhanced images. The image processing includes forming an enhanced modulation transfer functions (MTF) using a gain function (G) applied to the "raw" MTF. Embodiments of the single lens element include at least one diffractive feature (23) to reduce chromatic aberration. Single lens elements with at least one aspheric surface (S1, S2 or S1 and S2) are also disclosed.

摘要： An extended depth-of-field (EDOF) surveillance imaging system (8) that has a lens system (10) with a total lens power ϕ T and an amount of spherical aberration SA where 0.2λ ≤ SA ≤ 2λ. The lens system includes first lens group (G1) and a second lens group (G2). The first lens group has first and second confronting meniscus lens elements (L1, L2) that have an overall optical power ϕ 1 such that |ϕ1/ϕ T | ≤ 0.05. The second lens group has a doublet (D1) and a most imagewise positive lens element (L5). An aperture stop (AS) is arranged either between the first and second lens groups or within the second lens group. An image sensor (30) is arranged to receive the image and form therefrom a digitized electronic raw image. An image processor receives and digitally filters the digitized electronic raw image to form a digitized contrast-enhanced image.
