Abstract: A active stabilization system and a method for correcting a pointing direction of a camera to compensate for translational movements of the camera are described. The system actively stabilizes a pointing direction of the camera in accordance with a commanded pointing angle. A distance from the camera to a filming target is determined and one or more translational measurements associated with a translational movement of the camera are derived. A correction update is calculated as a function of at least the distance and the one or more translational measurements. The commanded pointing angle of the camera is adjusted based on the correction update to retain the filming target within a field of view of the camera.

An optical NRZ signal is transformed into a chirped RZ format by applying optical phase or frequency modulation at the data clock rate, and subsequently passing it through linear chromatic dispersion. The architecture required to perform this function can be implemented using a single Lithium Niobate substrate incorporating two modulation functions.

Abstract: A CT scanner comprises a rotatable gantry 1 carrying an X-ray source 3 which provides a fan-shaped beam of X-rays and an X-ray detector 10 which scans the X-ray intensity along a line in the plain of the beam. The gantry is rotatable about an axis A relative to a couch 2 which supports the patient under investigation. The X-ray detector 10 comprises two concentric X-ray masks exposed around a scintillator tube; the two masks having helical X-ray transmissive apertures, the helices being of opposed orientation so that rotation of the masks in opposite directions causes the exposed area of the scintillator tube to move along its length.
