  • Patent number: 7600689
    Abstract: Methods of and systems for illuminating objects using planar laser illumination beams having substantially-planar spatial distribution characteristics that extend through the field of view (FOV) of image formation and detection modules employed in such systems. Each planar laser illumination beam is produced from a planar laser illumination beam array (PLIA) comprising an plurality of planar laser illumination modules (PLIMs). Each PLIM comprises a visible laser diode (VLD, a focusing lens, and a cylindrical optical element arranged therewith. The individual planar laser illumination beam components produced from each PLIM are optically combined to produce a composite substantially planar laser illumination beam having substantially uniform power density characteristics over the entire spatial extend thereof and thus the working range of the system.

  • Patent number: 7527200
    Abstract: A hand-supportable planar laser illumination and imaging (PLIIM) based device having hand-supportable housing with a light transmission aperture. A linear image formation and detection (IFD) module is mounted within the housing, and has a linear array of image detection elements and also image formation optics with a field of view (FOV). When an object is presented within the FOV, the FOV focuses a linear image of the object onto the linear array. At least one planar laser illumination module (PLIM) is mounted on the support platform, with the linear IFD module, and produces a planar laser illumination beam (PLIB) spatially aligned with respect to the FOV and arranged in a coplanar relationship with at least a portion of the FOV. A laser beam despeckling mechanism is integrated in the device, for reducing speckle-pattern noise observed the linear digital images formed and detected at the linear array of image detection elements.

  • Patent number: 7513428
    Abstract: An imaging device including at least one imaging array and image formation optics that provide a field of view corresponding to the imaging array. At least one illumination module (which includes at least one source of coherent illumination) produces planar light illumination that substantially overlaps the field of view corresponding to the imaging array. Illumination control circuitry modulates the power level of illumination produced by the source of coherent illumination during each photo-integration time period of the imaging array to thereby reduce speckle noise in images captured by the imaging array. The illumination control circuitry preferably modulates the power level of illumination by controlling the number and/or duration of time periods corresponding to different power levels of illumination produced by the source of coherent illumination during each photo-integration time period of the imaging array.

  • Publication number: 20070194207
    Abstract: An improved wavefront sensor for characterizing phase distortions in incident light including optical elements that spatially sample the incident light and form a dispersed spot with a fringe pattern corresponding to samples of the incident light. An imaging device captures an image of the dispersed spot with said fringe pattern formed by said optical elements. And an image processor that analyzes the spectral components of the fringe pattern of a given dispersed spot to derive a measure of the local phase distortion without ambiguity in the corresponding sample of incident light. The optical elements may comprise refractive elements, diffractive elements or a combination thereof (such as a grism). The wavefront sensor may be part of an adaptive optic system (such as a large-aperture space telescope) to enable the measurement and correction of large phase steps across adjacent mirror segments of a deformable mirror.
