Patent number: 7643052Abstract: The present invention describes a self-contained omni-directional imaging device. The device is designed to contain within it all mechanic, electronic, optic and electro-optic components required for its operation, namely: omni-directional optics, image capture device, power source, illumination sources, transmitters, receivers and additional optional elements for enhanced capabilities. A preferred embodiment of the invention describes such a device housed inside a durable spherical structure, designed for deployment to potentially hazardous environments, enabling omni-directional view to those environments without endangering the viewer. The device is capable of acquiring and transmitting still or video images and audio streams to a remote, control and display unit located near the operator.Type: GrantFiled: November 25, 2002Date of Patent: January 5, 2010Assignee: Wave Group Ltd.Inventors: Ehud Gal, Gennadiy Liteyga, Reuven Eyal, Itzhak Kattan

Patent number: 7570437Abstract: In a first aspect, the present invention provides an omni-directional imaging assembly. In the preferred embodiment the assembly of the invention comprises a solid omni-directional lens comprising a vertical axis of symmetry; an upper surface, at least part of which is capable of reflecting rays that arrive from the inner side of the omni-directional lens; a transparent perimeter surface; a lower convex surface, at least part of which is capable of reflecting rays that arrive from the direction of the perimeter surface; and a transparent circular surface maintained in the lower convex surface around the vertical axis of symmetry. The light rays from a first 360 degrees, panoramic, scene are refracted by the transparent perimeter surface, are then reflected by the lower convex surface towards the upper surface, and then reflected by the upper surface towards the transparent circular surface, where they are refracted and exit the omni-directional lens.Type: GrantFiled: October 27, 2003Date of Patent: August 4, 2009Assignees: O.D.F. Optronics, Ltd., O.D.F. Medical Ltd.Inventors: Ehud Gal, Gennadiy Liteyga, Gil Graisman

Patent number: 7362516Abstract: The invention presents a wide-angle imaging assembly which comprises a main lens produced from an aspheric optical block. The aspheric optical block comprises a vertical axis of symmetry; a transparent upper surface, at least part of which is capable of reflecting rays that impinge upon it from the interior of the optical block; a transparent perimeter surface; and a transparent lower surface. The optical block is fabricated from material selected to enable optical transmittance of a specific spectral range. Light rays in the specific spectral range originating in a first scene, having a 360 degrees panoramic perimeter, are refracted by the transparent perimeter surface, enter the optical block, are then reflected by the upper surface towards the transparent lower surface, where they are then refracted by the transparent lower surface, and exit through it.Type: GrantFiled: July 3, 2003Date of Patent: April 22, 2008Assignees: O.D.F.

Patent number: 7075048Abstract: A method for determining azimuth and elevation angles of a radiation source or other physical objects located anywhere within an cylindrical field of view makes use of an omni-directional imaging system comprising of reflective surfaces, an image sensor and an optional optical filter for filtration of the desired wavelengths. The imaging system is designed to view an omni-directional field of view using a single image sensor and with no need for mechanical scan for coverage of the full field of view. Use of two such systems separated by a known distance, each providing a different reading of azimuth and elevation angle of the same object, enables classic triangulation for determination of the actual location of the object. The invention is designed to enable use of low cost omni-directional imaging systems for location of radiation sources or objects.Type: GrantFiled: March 1, 2005Date of Patent: July 11, 2006Assignee: Wave Group Ltd.Inventors: Ehud Gal, Reuven Eyal, Gil Graisman, Gennadiy Liteyga

Publication number: 20050117227Abstract: An imaging assembly comprises a first, essentially symmetric reflective surface, having a shape suitable to reflect a substantially panoramic view of an area surrounding it, and a second reflective surface, which is asymmetric with respect to said first reflective surface, viz., which is positioned, with respect to the axis of symmetry of said first reflective surface, such that its movement in one or more directions reflects different portions of the area reflected by said first reflective surface, and the optical properties of said second reflective surface are such that area imaged by it is magnified with respect to the same portion of the area imaged by the first reflective surface.Type: ApplicationFiled: September 21, 2004Publication date: June 2, 2005Inventors: Ehud Gal, Gennadiy Liteyga, Reuven Eyal, Gil Graisman
