Publication number: 20230184519Abstract: A safety assembly for use with a laser-directed energy weapon is disclosed. The assembly comprises a control system comprising a photodetector and a processing unit; and an optical device configured to attach to a target such that, when attached, the optical device provides a light beam to the photodetector. The processing unit is arranged to compare the received light beam against one or more predetermined attributes, and to permit the laser-directed energy weapon to fire only when the received light beam is determined to have the one or more attributes.Type: ApplicationFiled: May 10, 2021Publication date: June 15, 2023Applicant: MBDA UK LIMITEDInventors: Andrew PETERS, Jon DAW, Martyn Robert JENNINGS, William Michael George HALSTEAD, Colin BRIDGEWATER, Mark OWEN

Patent number: 8757064Abstract: Described herein is an optical fuze for a guided missile that comprises an array of a large number of optical apertures distributed about the outer surface of the missile. An optical waveguide network selectively couples the array of apertures to a laser source and to a photodetector such that light from the laser source is emitted by selected ones of said apertures, and light returned from a target is received by selected ones of said apertures and directed by said optical waveguide network to said photodetector. These apertures might be arranged to form a composite target images in a particular direction, and/or may be arranged to perform a sensing operation along selected directions. The optical proximity fuze described herein provides inherent flexibility in the way the fuze can be configured in the missile for optimisation for different applications.Type: GrantFiled: August 6, 2009Date of Patent: June 24, 2014Assignee: MBDA UK LimitedInventors: Martyn Robert Jennings, Lee Douglas Miller

Patent number: 8330088Abstract: A target scene generator for testing an imaging ladar in a Hard Ware in the Loop arrangement, such as might be employed for testing an optical seeker on a guided missile, the generator comprising an array of pixel elements, a photodetector for detecting incident light from a ladar a laser source for generating pulses of light representing returned ladar pulses, and a reconfigurable fiber network including an optical switch selectively coupling the laser to the pixel elements, and a controller which selectively reconfigures the fiber network, to present to selected pixel elements the pulses of light with selected time delay characteristics such that light emitted from the pixels represent light returned from a target illuminated by the ladar.Type: GrantFiled: November 10, 2009Date of Patent: December 11, 2012Assignee: MBDA UK LimitedInventors: Martyn Robert Jennings, Lee Douglas Miller

Patent number: 7606283Abstract: A laser device and a method of pumping a laser gain medium (R) comprise directing pulses of laser light from a pump laser (10) to a series of separate locations (11, 12, 13, 14, 15, 16 and 17) arranged longitudinally along the gain medium (R) in the direction of laser propagation. Each pulse of laser light generates a population inversion in an associated portion of the gain medium (R) just ahead of the laser photons. The pulses from the pump laser (10) are transmitted by a splitter (18) to the series of separate locations by optical delay lines (11, 12, 13, 14, 15, 16 and 17) and each delay line is arranged to pump a different portion of the gain medium to cause a localised population inversion. The pulse transmission delays deliver a sequence of pulses to the portions of the gain medium (R) such that each portion will in turn contribute to amplification of a laser propagating within the gain medium (R).Type: GrantFiled: July 27, 2006Date of Patent: October 20, 2009Assignee: MBDA UK LimitedInventors: Martyn Robert Jennings, Lee Douglas Miller
