    Abstract: An imaging apparatus and method are provided for improving discrimination between parts of a scene enabling enhancement of an object in the scene. A camera unit is arranged to capture first and second images from the scene in first and second distinct and spectrally spaced apart wavebands. An image processing unit processes the images so captured and processes polarimetric information in the images to enable better discrimination between parts of the scene. An image of the scene, including a graphical display of the polarimetric information, may be displayed on a visual display unit thus enhancing an object in the scene for viewing by a user. Correlation parameters indicating, possibly on a pixel-by-pixel basis, the correlation between the actual image intensity at each angle of polarization and a modelled expected image intensity may be used to enhance the visibility of an object.

    Abstract: A spectral camera for producing a spectral output is disclosed. The spectral camera has an objective lens for producing an image, a mosaic of filters for passing different bands of the optical spectrum, and a sensor array arranged to detect pixels of the image at the different bands passed by the filters, wherein for each of the pixels, the sensor array has a cluster of sensor elements for detecting the different bands, and the mosaic has a corresponding cluster of filters of different bands, integrated on the sensor element so that the image can be detected simultaneously at the different bands. Further, the filters are first order Fabry-Perot filters, which can give any desired passband to give high spectral definition. Cross talk can be reduced since there is no longer a parasitic cavity.

    Abstract: A calibration system (300) for a detector (328) includes a base member (302), a plurality of radiation sources (304)fixedly attached to the base member, and a positioning mechanism (306) attached to the base member. Each radiation source (394) is maintained at a different temperature and is configured to emit electromagnetic radiation. The positioning mechanism includes a movable member (308) having a single degree of freedom with respect to the base member (302), and a plurality of optical elements arranged (310) on the movable member. Each optical element corresponds (310) to one of the radiation sources (304) and each optical element is configured to at least be movable between a calibration position and a non-calibration position. When the optical element is in the calibration position, the optical element is configured to receive the electromagnetic radiation from its corresponding radiation source and to reflect the electromagnetic radiation to a detector.

    Abstract: The invention relates to a system and a method for optical measurement of a target, wherein the target is illuminated, either actively illuminated, reflecting ambient light, or self illuminating, and a measurement light beam received from the target or through it is detected. The prior art optical measurement systems generally include mechanical filter wheels and photomultiplier tubes, which cause the equipment to be expensive, large-sized and often not sufficiently accurate and stable. The objective of the invention is achieved with a solution, in which the illuminating light beam and/or measurement light beam is led through a Fabry-Perot interferometeror a set of two or more Fabry-Perot Interferometers, and the Fabry-Perot interferometer or a set of two or more Fabry-Perot Interferometersis controlled into different modes during the measurement of a single target. The invention can be applied inoptical measurements where, for example, reflectance, absorption of fluorescence of the target is measured.

    Abstract: Eine Vorrichtung zur Bestimmung der Konzentration von NO 2 in Gasgemischen, insbesondere Abgasen von Dieselmotoren, umfasst eine Lichtquelle zur Ausgabe von Licht in einen Lichtweg; eine Sensoreinrichtung zum Empfang zumindest eines Teils des über den Lichtweg zur Sensoreinrichtung vordringenden Lichtes, wobei der Verlauf des Lichtweges so gewählt ist, dass dieser das zu untersuchende Gas durchsetzt, wobei die Sensoreinrichtung so gestaltet ist, dass diese Signale liefert die das Spektrum des erfassten Lichtes beschreiben; und eine Auswertungsschaltung zur Auswertung der durch die Sensoreinrichtung generierten Signale, wobei die Sensoreinrichtung derart gestaltet ist, die Bestimmung der NO 2 -Konzentration erfolgt indem die Bestimmung innerhalb eines eingeschränkten spektralen Bereiches erfolgt, in dem eine ausgeprägte absolute oder relative Variation des Absorptionskoeffizienten des NO 2 und eine geringe absolute oder relative Variation der weiteren Gase vorliegt. Hierdurch ist es möglich, für die Konzentration von NO 2 im Abgas eines Verbrennungsmotors indikative Signale über einen langen Zeitraum hinweg zuverlässig zu generieren.
