The processing may optionally be nonlinear. Other imaging systems and methods include optics having one or more phase modifying elements that modify wavefront phase to form an optical image. A detector generates electronic data having one or more image attributes that are dependent on characteristics of the phase modifying elements and/or the detector.

Abstract: A singlet imaging system for imaging an object onto a detector includes a lens configured for producing transverse ray intercept curves which are substantially straight, sloped lines. A wavefront coding element is formed on a surface of the lens and configured such that a modulation transfer function of the lens and wavefront coding element, combined, exhibits reduced variation, over a range of spatial frequencies and caused, at least in part, by aberrations of the lens, as compared to a modulation transfer function of the lens alone, without the wavefront coding element. A post processor is configured for generating an improved modulation transfer function, over the range of spatial frequencies, as compared to the modulation transfer function of the lens and the wavefront coding element.

Abstract: Zoom lens systems and methods for imaging incoming rays over a range of ray angles are disclosed. The incoming rays are characterized by at least phase. The zoom lens system includes an optical axis and is characterized by a plurality of modulation transfer functions (MTFs) corresponding at least to the range of ray angles. The zoom lens system includes an optical group disposed along the optical axis, including at least one variable optical element that has a variable focal length selectable between at least two distinct focal length values. The optical group also includes a wavefront coding element. The wavefront coding element alters at least the phase of the incoming rays, such that the plurality of MTFs corresponding to the range of ray angles, for each one of the two distinct focal length values, are less sensitive to misfocus-like aberrations than a corresponding system without the wavefront coding element.

Abstract: A system, method and software product to optimize optical and/or digital system designs. An optical model of the optical system design is generated. A digital model of the digital system design is generated. Simulated output of the optical and digital models is analyzed to produce a score. The score is processed to determine whether the simulated output achieves one or more goals. One or more properties of at least one of the optical model and the digital model is modified if the goals are not achieved. The analyzing, processing and modifying is repeated until the goals are achieved, and an optimized optical system design and optimized digital system design are generated from the optical and digital models.

Abstract: An imaging system for imaging an object onto an image plane. An optical arrangement forms an intermediate image of the object at an intermediate plane with a first value of axial resolution. The imaging system also includes a digital processor configured to process the intermediate image to form a final image of the object at the image plane. The imaging system further includes a specially designed optical element that cooperates with the optical arrangement and the digital processor to define a second value of axial resolution that is greater than the first value.

Abstract: An interference contrast imaging system images phase objects. The system includes an illumination source, illumination optics, polarizing optics for splitting the illumination into orthogonal polarizations and for recombining the polarizations, objective optics that form an image at a detector, a wavefront coding element and a post processor for processing the image by removing a phase shift imparted by the wavefront coding element. The wavefront coding element has an aperture, is between the phase object and the detector, and provides an altered optical transfer function of the imaging system by imparting the phase shift to the illumination transmitted through the wavefront coding element. The altered optical transfer function is insensitive to an object distance between the phase object and the objective optics over a greater range of object distances than would be provided by an optical transfer function of a corresponding interference contrast imaging system without the wavefront coding element.

Abstract: An infrared imaging system for imaging infrared radiation from an object onto a detector includes optics configured for producing, with the infrared radiation, transverse ray intercept curves that are substantially straight, sloped lines. A wavefront coding element is configured such that a modulation transfer function of the optics and wavefront coding element, combined, exhibits reduced variation, over a range of spatial frequencies and caused, at least in part, by thermal variation within the imaging system, as compared to a modulation transfer function of the optics alone, without the wavefront coding element. A post processor is configured for generating an improved modulation transfer function, over the range of spatial frequencies, as compared to the modulation transfer function of the optics and the wavefront coding element.
