  • Publication number: 20110019032
    Abstract: A multi-spectral video camera and corresponding method have an optical arrangement for collecting light, a light splitting prism for splitting the light into a number of spatially separated channels of distinct spectral ranges, and a corresponding number of image sensor arrays. An electronic control and processing system receives sensed pixel data from each of image sensor arrays, analyzes the pixel data separately for each of the image sensor arrays to determine an exposure parameter for each of the sensor arrays, and actuates each of the sensor arrays to capture a subsequent image frame with an effective exposure individually set for each sensor array in accordance with the corresponding exposure parameter. The camera also preferably performs independent contrast enhancement corrections for each spectral channel of the camera.

  • Publication number: 20100241385
    Abstract: A method and system are for measuring and correcting shifts in the boresight, effective focal length, and focus of an optical system that are caused by temperature variations. The method can be used for systems which can be expected to operate in situations where the temperature variations are large, e.g. a FLIR system of a fighter plane, and also where the temperature variations can be very small however high accuracy is needed. The invention is based on placing radiation emitting sources before and as close as possible to the first optical element of the optical system and measuring the thermally induced shifts of the locations of the images of the radiation emitting sources on the surface of the detector of the optical system.

  • Patent number: 7714261
    Abstract: A system and method for protection of aircraft against surface-to-air missiles deploys sensors to provide coverage around an airport The use of a fixed (or slow moving) set of sensors around the airport allows detection of missile threats to all aircraft using the airport without requiring each individual aircraft to be provided with a threat detection system. Information about a detected threat is then typically transmitted in real time directly to the aircraft under threat to allow timely deployment of aircraft-based countermeasures. The detection system and method preferably employ spaced-apart sensors with overlapping fields of view to provide enhanced tracking through triangulation and reduced false alarm rates by redundancy of information. Airborne systems with overlapping coverage may be also used.

  • Publication number: 20100043444
    Abstract: A method for implementing a system and a device for enhancing the starting process of a turbine engine by use of at least one solid mass of oxidizing-species-releasing material, ORM, selected as a solid oxidizer, or SO, and/or as an oxidizing-species-releasing burning substance, or ORBS. The ORM is introduced into the combustion chamber of the turbine engine and the starting process of the turbine engine is initiated, by help of the igniter and in association with the mass of ORM, to enhance the starting process. In operation, an ORM selected as an SO releases gaseous oxygen when heated to decompose, while an ORM chosen as an ORBS discharges oxidizing species when ignited to burn. An ORM such as an SO or an ORBS may operate alone or in various combinations of both. The ORM is configured to release a predetermined mass flow rate of oxidizing species or of gaseous oxygen.
