Abstract: A device for monitoring radiation emitted by luminophores present in an analyte fluid of a wiregrid biosensor. The monitoring device comprises a non-polarized light source (41) for illuminating the wiregrid biosensor for exciting fluorescent labels arranged in the analyte fluid of said biosensor. A detector (71) detects radiation emitted by the labels after excitation. A polarizing filter (53) is arranged in between the transparent substrate and the detector for suppression of background emission radiation from labels positioned outside apertures in the wiregrid, in the analyte fluid.

Abstract: A radiation imaging system is configured by a collimator 30A including a detector 21 with a discrete detection pixel corresponding with a pixel and a plurality of radiation passages 31 and looks into a plurality of detectors 21 through one radiation passage 31 to set a step width of rotation around a rotation center axis X1 only for an angle ?p made by lines provided by connecting a center detector 21 of the radiation passage 31 and the adjacent two detectors 21. In the case of generating a flat plane projection image for one direction, radio-graphing is carried out on a projection image in a plurality of predetermined angle positions (??p, 0, +?p) in the circumferential direction of the rotation center axis X1 and thereby one plane projection image is obtained.

Abstract: An apparatus for determining the position of an x-ray beam relative to a desired beam axis. Where the apparatus is positioned along the beam path so that a thin metal foil target intersects the x-ray beam generating fluorescent radiation. A PIN diode array is positioned so that a portion of the fluorescent radiation is intercepted by the array resulting in an a series of electrical signals from the PIN diodes making up the array. The signals are then analyzed and the position of the x-ray beam is determined relative to the desired beam path.

Abstract: A scanning circuit for improving the signal-to-noise ratio of the output of detector elements in an infrared detector array and for providing a more complete representation of objects within the detector elements field of view is disclosed. The circuit comprises circuitry for accumulating charges representative of the outputs of the detector elements during a charge accumulation interval and circuitry for outputting signals representative of the accumulated charges to external circuitry during an output interval. The charge integration interval is longer in duration than the output interval, thus providing increased detector element integration time.
