摘要： 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.

摘要： 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.

摘要： A method and control system for forming workpiece surfaces with at least a portion being non-rotationally symmetric (i.e., axis asymmetric) is provided. In one aspect, a slow tool servo system is provided to fabricate a surface having at least an axis asymmetric portion, and optionally, a superimposed axis symmetric asphere or spherical portion. A workpiece is mounted on a spindle and a tool is mounted to a translatable tabletop surface. The z position of the contact point of the workpiece and working tool is determined as a function of the x position of the same contact point and as a function of the angle of rotation of the spindle about the spindle axis. By making the z position of the contact point a function of both the angle of spindle rotation and the x position, the lateral and longitudinal position of the working tool can be moved at designated spindle rotation angles to form a surface having both axis asymmetric and axis symmetric asphere or spherical portions.

摘要： A detector assembly is configured for characterizing electromagnetic energy that propagates along a light path. At least a component of the electromagnetic energy carries electromagnetic energy information along the light path. The detector assembly includes a first detector array arranged along the light path and having photosensitive elements aligned to receive at least some of the electromagnetic energy, including the component. The photosensitive elements selectively absorb a first portion of the component and produce a first set of electrical image data, based at least in part on the electomagnetic energy information, in response to the component. At least some of the photosensitive elements are at least partially transparent so that they selectively pass a second portion of the component to continue along the light path.

摘要： Systems and methods reduce aberrations in a wavefront imaged by an optical system having a non-linear detector. A wavefront of electromagnetic radiation from an object imaged to the non-linear detector is encoded. Data from the non-linear detector is digitally converted to form a digital representation of the image captured by the non-linear detector. The detected image is linearized to form a linearized image. The linearized image is filtered to reverse effects of wavefront coding to form a final image.

摘要： Low height imaging systems may include one or more optical channels and a detector array. Each of the optical channels may be associated with one or more detectors of the array, have one or more optical components and a restrictive ray corrector, and be configured to direct steeper incident angle field rays onto the detectors. Alternatively, each of the optical channels may be associated with at least one detector, and have an aspheric GRIN lens. Another low height imaging system has an array of detectors and a GRIN lens having a surface with wavefront coding and configured to direct steeper incident angle field rays onto more than one of the detectors. One method forms a lens with wavefront coding. The method includes positioning a lens in a mold; and curing material onto a surface of the lens to form an aspheric surface of the lens with wavefront coding.

摘要： An image processing method includes the steps of wavefront coding a wavefront that forms an optical image, converting the optical image to a data stream, and processing the data stream with a filter kernel to reverse effects of wavefront coding and generate a final image. By example, the filter set kernel may be a reduced filter set kernel, or a color-specific kernel. Methods and systems are also disclosed for processing color images, such as by separating color and spatial information into separate channels. Methods and systems herein are for example useful in forming electronic devices with reduced opto-mechanical, opto-electronic and processing complexity or cost.
