  • Patent number: 8760516
    Abstract: A task-based imaging system for obtaining data regarding a scene for use in a task includes an image data capturing arrangement for (a) imaging a wavefront of electromagnetic energy from the scene to an intermediate image over a range of spatial frequencies, (b) modifying phase of the wavefront, (c) detecting the intermediate image, and (d) generating image data over the range of spatial frequencies. The task-based imaging system also includes an image data processing arrangement for processing the image data and performing the task. The image data capturing and image data processing arrangements cooperate so that signal-to-noise ratio (SNR) of the task-based imaging system is greater than SNR of the task-based imaging system without phase modification of the wavefront over the range of spatial frequencies.

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. A signal processor subdivides the electronic data into one or more data sets, classifies the data sets and independently processes the data sets to form processed electronic data.

  • Patent number: 8164040
    Abstract: An imaging system includes a detector for receiving electromagnetic energy and generating sampled data in accordance with the electromagnetic energy so received. The detector is characterized by a threshold point such that the sampled data is in one of two states: i) below threshold, when the intensity of the electromagnetic energy so received is less than the threshold point; and ii) above threshold, when the intensity of the electromagnetic energy is greater than the threshold point. The imaging system also includes saturation optics for providing a characteristic of the sampled data, wherein the characteristic of the sampled data when below threshold is different from the characteristic of the sampled data when above threshold.

    Abstract: A method for generating an output image of a scene is disclosed. A detector of a task-based imaging system includes a plurality of pixels, and the scene includes at least one object located at a given object distance within a range of object distances between the object and the imaging system. The method includes capturing a high resolution image of the scene, converting the high resolution image into an image spectrum of the scene, determining a defocused optical transfer function (OTF) of the imaging system over the range of object distances and determining a pixel modulation transfer function (MTF) over the plurality of pixels. The method also includes multiplying the image spectrum with the OTF and the MTF to generate a modified image spectrum of the scene, converting the modified image spectrum into a modified image of the scene, and generating the output image from the modified image.
