Patent number: 11466966Abstract: A localized laser-based interceptor for kites balloons and UAVs comprises a laser and a large aperture optical beam delivery system with adjustable focal distance and spot size. The spot-size is adjusted for optimal damage performance on plastic targets, as a function of the distance from the target, its velocity across the laser beam spot and where the extent of the danger zone for personnel and equipment is limited by the fast expansion of the illuminating laser beams. The optical design ensures diverging beam to minimize the hazardous range of the system.Type: GrantFiled: July 4, 2019Date of Patent: October 11, 2022Assignees: THE STATE OF ISRAEL ISRAEL NATIONAL POLICE, OPTIDEFENSE LTD.Inventors: Yehuda Ben Ami, Amiel Ishaaya, Abraham Aharoni

Patent number: 10365298Abstract: A detection arrangement and method for directing the sensitivity of an optical knife-edge detection system to its optimal operating point. This is referred to as an increase in the detection dynamic range of the system with advantageous applications for detecting motion of a surface such as for Atomic Force Microscopy as well as detecting acoustic vibrations on unstable surfaces. A pair of parallel reflecting surfaces, such as an optical slab waveguide, serve to reflect the sensing beam back onto the knife-edge detector once it is shifted off its sensing range. Allowing multiple reflections, the sensing beam is maintained on the knife-edge detector even at large angular offsets from the optimal operating point of the basic knife-edge detector. Use of a modified arrangement, with two knife-edge detectors at quadrature ensures near-optimal sensitivity at a detection dynamic range up to forty-fold larger than that of the basic knife-edge system.Type: GrantFiled: November 24, 2014Date of Patent: July 30, 2019Assignee: Technion Research & Development Foundation LimitedInventor: Abraham Aharoni

Patent number: 9846235Abstract: There are provided methods and systems for producing a wave-beam having substantially constant lateral extent over a desired range of distances, and interrogation and response system and methods utilizing the same. The method for producing a wave-beam having substantially constant lateral extent includes generating a plurality of at least partially incoherent constituent wave-beams having different divergences and directing the plurality constituent wave-beams to propagate along substantially parallel propagation axes such that the constituent wave-beams at least partially overlap and superpose to form a combined wave-beam. The divergences and intensities of the constituent wave-beams are selected such that the combined wave-beam has a desired substantially constant extent over a desired range of distances along said propagation axes.Type: GrantFiled: August 8, 2013Date of Patent: December 19, 2017Assignee: Israel Aerospace Industries Ltd.Inventors: Abraham Aharoni, David Lou Alon, Aharon Yifrach

Patent number: 9277330Abstract: A system and method for directional sound sensing directs an optical sensing beam to an object of interest having a rough surface that vibrates acoustically. The light is reflected thereby and scattered as a speckle pattern that includes multiple speckles having a random distribution of phase offsets. A detector array having multiple detector elements receives and detects the speckle pattern and produces signals that are linearly proportional to phase modulation of the speckles. A summer receives signals from at least two of the detector elements that are offset at different phases and sums the received signals to generate a non-vanishing signal representative of an acoustic signal.Type: GrantFiled: September 25, 2009Date of Patent: March 1, 2016Assignee: TECHNION RESEARCH AND DEVELOPMENT FOUNDATION LTD.Inventors: Abraham Aharoni, Mordechai Segev, Zvi Katz

Patent number: 5610734Abstract: An optical system is disclosed which focuses a polychromatic source to an extended focal pencil. The implementation makes use of two holographic optical elements (HOEs) fabricated and aligned to form a deliberate longitudinal color dispersion, but to alleviate lateral chromatic effects. Consequently, the HOE doublet focuses different wavelengths of the source to different locations along the optical axis. The strong intensity of the focused wavelengths dominate at each location, so that the overall beam has a near-diffraction-limited 1/e.sup.2 spot size and suffers only relatively weak background illumination. An alternative optical system using bulk lenses and several possible applications for the device are also described.Type: GrantFiled: February 9, 1995Date of Patent: March 11, 1997Assignee: Board of Trustees Leland Stanford, Jr. UniversityInventors: Abraham Aharoni, Joseph W.
