    • An imaging system is characterized at least by an ambiguity function (“AF”) and a point spread function (“PSF”). The AF is a function of parameters u and v related to a misfocus parameter ψ; the PSF is at least a function of ψ. The system includes (1) an image recording device, (2) an optical arrangement for imaging an object to the image recording device, and (3) a post processor that renders an in-focus electronic image over a range of distances between the object and the optical arrangement. The optical arrangement alters phase such that a main lobe of the AF is broader in v for a specific u. The PSF has a functionally different form for a specific ψ, in comparison to a PSF characterizing the system when the optical arrangement does not alter the phase for those specific values of u and ψ over the range of distances.
    • 成像系统至少由歧义函数(“AF”)和点扩散函数(“PSF”)表征。 AF是与误聚焦参数psi相关的参数u和v的函数; PSF至少是psi的函数。 该系统包括(1)图像记录装置,(2)用于将对象成像到图像记录装置的光学装置,以及(3)后处理器,其在对象之间的距离范围内呈现对焦电子图像 和光学装置。 光学布置改变相位,使得对于特定的u,AF的主瓣在v中更宽。 与特定系统的PSF相比,PSF具有功能上不同的形式,当光学布置不改变在距离范围内u和psi的那些特定值的相位时。
