Anamorphic Patents (Class 359/668)
  • Patent number: 10133168
    Abstract: A compact light projection system. The light projection system includes a light source, an anamorphic reflector assembly, and a correction element that is configured to mitigate aberration. The light source is configured to emit image light. The anamorphic reflector assembly includes a first surface and a second surface. The first surface is configured to reflect the image light toward the second surface which reflects the reflected image light to output it from the anamorphic reflector assembly. And the first surface and the second surface are both curved and non-rotationally symmetric such that the light output from the anamorphic reflector assembly is collimated image light. The collimated image light is optically corrected based in part on mitigation of aberration by the correction element.

  • Patent number: 8872875
    Abstract: An single-pass imaging system utilizes a light source, a spatial light modulator and an anamorphic optical system to form a substantially one-dimensional high intensity line image on an imaging surface (e.g., the surface of a drum cylinder). The light source and the spatial light modulator are used to generate a relatively low intensity two-dimensional modulated light field in accordance with an image data line such that each pixel image of the line is elongated in the process (Y-axis) direction. The anamorphic optical system utilizes a cylindrical/acylindrical optical element to anamorphically image and concentrate the modulated light field in the process direction to form the substantially one-dimensional high intensity line image. The line image is generated with sufficient energy to evaporate fountain solution from the imaging surface. The imaging system simultaneously generates all component pixel images of the line image, thus facilitating a printing apparatus capable of 1200 dpi or greater.

  • Patent number: 8817382
    Abstract: A light modulation device side lens group has different powers in the longitudinal direction and the lateral direction of a liquid crystal panel. Therefore, as the entire system of the optical projection system, the light modulation device side lens group has different magnification in the longitudinal and lateral directions. Therefore, it is possible to make the aspect ratio of an image of the liquid crystal panel different from the aspect ratio of an image projected on a screen. That is, conversion can be performed on an aspect ratio. At this time, a distance p between each focus or a diaphragm and the screen SC side end surface of the light modulation device side lens group satisfies the conditional expressions, so it is possible to achieve a predetermined or higher telecentricity in both states, that is, a first operating state and a second operating state.

The material is provided with plural spaced curvilinear, optically matched slots and/or recesses through which an x-ray beam is directed. The focal length of the material may be decreased or increased by increasing or decreasing, respectively, the number of slots (or recesses) through which the x-ray beam is directed, while fine tuning of the focal length is accomplished by rotation of the material so as to change the path length of the x-ray beam through the aligned cylindrical slots. X-ray analysis of a fixed point in a solid material may be performed by scanning the energy of the x-ray beam while rotating the material to maintain the beam's focal point at a fixed point in the specimen undergoing analysis.

  • Patent number: 8009929
    Abstract: A digital camera includes a tri-axial acceleration sensor. The CPU determines a direction of the camera at a time of image capturing, on the basis of a gravitational direction which is detected by the tri-axial acceleration sensor, calculates a parameter for projection-correcting a captured image in a predetermined direction on the basis of the direction of the camera, and corrects a distortion of the captured image by using the parameter.

  • Patent number: 7995282
    Abstract: A pair of optical prisms arranged in a complementary relationship provides for anamorphic magnification and cooperates with a refractive or diffractive cylindrical lens element, the later of which generates an aberration that at least partially compensates an aberration generated by the pair of optical prisms. The refractive or diffractive cylindrical lens element is rotated out of normal with respect to the optic axis of the system so as to provide for reflecting stray light away from the optic axis.

  • Patent number: 7885012
    Abstract: An illuminator (10) for producing a radiation spot (120) on a workpiece (110) comprises a laser light source (20) and a beam-shearing optical system (30). Fine structure (160) generated by an integrator (80) of laser light source (20) in integrated beams (90) as a result of path length differences among coherent light beams (70) from emitters (60) of lasers (40) is sheared by the inclusion of beam-shearing optical system (30) into illuminator (10). Beam-shearing optical system (30) allows illuminator (10) to produce a radiation spot (120) in which the fine structure (160) is spread so that scanning of radiation spot (120) does not produce the striations (140) in scanned patch (170) that are obtained with prior art illuminators.
