  • Patent number: 7336823
    Abstract: A method and a device to provide a full representation of an object having a wide dynamic intensive range and maintain a good sensitivity for signal levels throughout the whole intensive range is disclosed. The wide intensive range is divided into a predetermined number of intensive intervals inside the wide intensive range. The intensive intervals are provided at the side of each other or are partly overlapping. The same number of interval representations of the object are provided as the predetermined number of intervals. Each interval representation is adapted to one individual of the intervals. The sizes, acquisition parameters and/or calibration parameters of the interval representations are adapted to each other. The interval representations are combined such that their respective intervals are provided in the same full representation.

  • Patent number: 7304779
    Abstract: A device for converting light from, for example, a laser, VCSEL (vertical cavity surface emitting laser) or light emitting diode/diodes to a plane of propagation, comprising a collimated or focused light emitter, characterized in that a full or a portion or several portions of a rotational symmetrical double reflecting component is fixedly provided coaxially in the path of beams from the collimated or focused light emitter so that the light is deflected in a desired angled plane of propagation which extends up to 360° around the double reflecting component.

  • Publication number: 20070252973
    Abstract: Position detecting device, comprising a photo detection element array having n segments and a parallel arithmetic processing portion that is arranged to identify the segment having maximum intensity by comparing the output values (OV) from the segments of the photo detection element array. The parallel arithmetic processing portion comprises at least one comparing stage that is arranged to successively select/deselect the segments, until the segment having maximum intensity is selected, the first stage receiving the output values OV from respective photo detection element segments as input segments (IS) and any additional stage receiving the output values OV from the preceding stage as input segments IS. There is also provided a rangefinder comprising the position detecting device.

  • Publication number: 20040232333
    Abstract: A method and a device to provide a full representation of an object having a wide dynamic intensive range and maintain a good sensitivity for signal levels throughout the whole intensive range is disclosed. The wide intensive range is divided into a predetermined number of intensive intervals (INT1 to INT3) inside the wide intensive range. The intensive intervals are provided at the side of each other or are partly overlapping. The same number of interval representations (IM1 to IMn; F1 to Fn; T1 to Tn) of the object are provided as the predetermined number of intervals. Each interval representation is adapted to one individual of the intervals. The sizes, acquisition parameters and/or calibration parameters of the interval representations (IM1 to IMn; F1 to Fn; T1 to Tn) are adapted to each other. The interval representations respective intervals are provided in the same full representation (18; 18′; 20).

  • Patent number: 5604346
    Abstract: An arrangement for recording an IR image of an object. The arrangement has a focal plane array (FPA) of IR detectors and an optic which images the object on the focal plane IR detector array. At least one temperature reference is arranged in the beam path of the focal IR detector array. At least one IR reference detector is assigned as a reference among the IR detector elements in this array. Each temperature reference is coordinated with at least one of the IR reference detector elements so that each of the IR reference detector elements is impinged upon by radiation deriving essentially solely from one of the temperature references. An IR detector reference output signal is intended to be produced for each temperature reference. Each IR reference output signal is intended to set an individual reference level for the output signals from the remaining IR detector elements in the IR detector array.
