  • Patent number: 9810887
    Abstract: A quadric reflector can have an approximately conical shape. The shape can tapers from a wide base to an apex. The apex can include an aperture, a mirror, and a set of one or more optical elements. A mirror can be positioned within an overhang enclosure of the device in a plane approximately parallel to a circular cross section of the conical shape. The mirror can reflect environmental light that is reflected by the quadric reflector into the aperture or reflect light emitting from the aperture onto the quadric reflector. The overhang enclosure can have a substantially conical shape which eliminates secondary reflection resulting from the environmental light reaching the aperture twice. Using the overhang enclosure to absorb the secondary reflection eliminates or minimizes banding.

  • Patent number: 8542289
    Abstract: In a typical two-dimensional rectilinear image, all pixel widths are constant across the image. If the two-dimensional rectilinear image is mapped to a cylindrical surface, the pixels at the edge of the image are viewed at an angle, making the effective width of the pixels at the edge smaller than the effective width of the pixels in the interior of the image. This problem may be solved by applying a tuned distortion curve to the two-dimensional rectilinear image, which makes the pixels near the edge of the image wider than pixels in the interior of the image. When pixels that have been distorted in this manner are mapped to a cylindrical surface, the effective pixel width is uniform. A lens with a tuned distortion curve built into its optical profile captures at least a portion of the surrounding imagery such that the resultant image has uniform resolution when projected onto a virtual cylinder centered around a viewer.

    Abstract: This invention is a wide field surveillance optical system with inherent features being, non mechanical, compact, high resolution, a field of view up to two pi steradians solid angle. The optics design uses a single optical system and multiple flat image collection devices. Multiple fiber plates translate the image off of the curved image surface to a plane for flat image collection devices. The fiber plates also act to translate the image into a larger volume as compared to the curved image surface, allowing required volume for the multiple image collection devices. This invention uses a single optical system with multiple CCD or CMOS detectors. Advantages over prior art are simple optical designs, rugged optics because it can be manufactured as a single piece, and wider field of view without the sacrifice of resolution.

A steerable beam splitter can be provided to direct images to the full field imager and the zoom imager. The panoramic imaging system can be used in a number of different areas, for example surveillance or reconnaissance systems or in a sense and avoid type of collision avoidance system for aircraft including unmanned aerial vehicles.

  • Patent number: 8094183
    Abstract: A panoramic imaging device comprises: a photodetector array; a lens array having, on one plane, a center lens for receiving light in a front range of 36° to form a central unit image on the photodetector array, and left and right side lenses for receiving lights in left and right ranges each of 72° in capture angle of 180°; and four prisms in two pairs placed facing the side lenses. The two pairs of left and right prisms (more inclined and less inclined pairs) collect lights in divided two pairs of left and right ranges each of 36° in the 72° range (pairs closer to, and farther from, the front range), respectively, to form four side unit images on the photodetector array which are combined with the central unit image to reproduce a panoramic image without using wide-angle lenses or complex image correction process.

  • Patent number: 8072693
    Abstract: An optical system is adapted to form an image having a full 360° angle of view on an image plane. The optical system includes a front unit having at least two reflecting surfaces, each rotationally symmetric about a center axis, and a rear unit that is rotationally symmetric about the center axis and has positive power. The first reflecting surface is located opposite to an entrance pupil, and the second reflecting surface is located on the same side as the first reflecting surface. The entrance pupil in a section including the center axis is located between the outer periphery of the first reflecting surface and the outer periphery of the second reflecting surface. A light beam coming from afar passes through the front unit and the rear unit in order, forming an image at a position of an image plane off the center axis.

  • Patent number: 8035680
    Abstract: Digital data acquired from individual cameras and images converted to digitized images are projected onto virtual 3D screens, which can be generated by a computer. This can be realized by way of 3D-accelerated hardware. The images are not, however, projected in 3D. The virtual 3D scenario with the current camera images is projected and presented to the users in 2D. This process makes it possible to use simple cameras (2n) with single lenses. There is no need to use cameras with zoom technology.

  • Patent number: 8005314
    Abstract: A high speed, high-resolution flow imaging system is modified to achieve extended depth of field imaging. An optical distortion element is introduced into the flow imaging system. Light from an object, such as a cell, is distorted by the distortion element, such that a point spread function (PSF) of the imaging system is invariant across an extended depth of field. The distorted light is spectrally dispersed, and the dispersed light is used to simultaneously generate a plurality of images. The images are detected, and image processing is used to enhance the detected images by compensating for the distortion, to achieve extended depth of field images of the object. The post image processing preferably involves de-convolution, and requires knowledge of the PSF of the imaging system, as modified by the optical distortion element.

  • Patent number: 7974015
    Abstract: A center lens for collecting light in a center range and left/right lenses for collecting light in left/right ranges are supported in one plane to form center and left/right unit images. A microprocessor combines the unit images into a wide-angle image. The left/right optical lenses are placed on left-right direction line parallel to the wide-angle direction, while the center lens is placed distant from the left/right lenses above the direction line. Prisms are placed in front of the left/right lenses, and a toroidal lens to vertically modify the light path for light convergence onto each lens is placed in front of the prisms. The toroidal lens has a vertically curved surface having an axis coinciding with the direction line, and a horizontally cured surface having an axis coinciding with a vertical line passing through the center lens. This device can obtain a wide-angle image with a vertically large picture angle.

  • Patent number: 7782357
    Abstract: Techniques to minimize problems with dead zones associated with panoramic cameras are described. A dead zone is an area about a zero degree boundary where a three hundred and sixty degree panoramic image is split so that a two-dimensional panorama can be rendered. Redirection of the zero degree boundary to a position where no object appears is described that prevents an object located in the dead zone from being split between margins of the panorama. Another technique involves reproducing one or more portions of the image that appears at one margin adjacent to an opposite margin so that an object in the dead zone that would normally be split is reproduced in whole. The described techniques may be implemented in a panoramic camera endpoint device or in a client device remote from a camera. The techniques may be applied to live video or to previously recorded video.

    Abstract: A panoramic lens includes an aspherical convex surface and an aspherical concave surface. The convex surface includes a transparent portion and an internally reflective portion, and the concave surface also includes a transparent portion and an internally reflective portion. Light from a 360-degree surrounding scene enters the panoramic lens through the transparent portion of the convex surface, is reflected by the internally reflective portion of the concave surface, is reflected by the internally reflective portion of the convex surface, and exits the panoramic lens through the transparent portion of the concave surface as a narrow column of light beams. Light beams containing image data can be provided to the transparent portion of the concave surface, and those beams will follow this same optical path through the panoramic lens in reverse to project a panoramic image out from the transparent region of the convex surface.
