    Abstract: Method and apparatus for screening objects using Raman scattering to detect the presence of predefined substances or classes of substances, which may be hazardous, toxic or explosive. Radiation, e.g. light generated by a laser 14, is supplied to an incident region 11 of an object 10. Scattered radiation is collected from a collection region 13 on the surface of the object. spaced from the incident region. The characteristics of the scattered radiation include Raman features related to the predefined substances. The Raman features allow the presence or absence of the predefined substances to be determined. The object may be a package or envelope sent via the postal services. Alternatively, the apparatus may be used to identify hazardous substances carried under clothing by a person.

    Abstract: A method of identifying radiation detected in a wall-less proportional gas counter providing a stable pulse height spectrum. The method comprises i) transforming the detected pulse height spectrum (dn/dx) in accordance with the transform u=x 1/2 where x represents the energy of the detected pulses in the original pulse height spectrum; ii) generating a normalized spectrum in u-space comprising a representation of dn/du as a function of u, where n is the detected pulse count as a function of x; iii) deconvoluting the normalized spectrum in u-space to enhance the spectrum; and iv) determining from the enhanced spectrum the energy (or energies) and/or the intensity (or intensities) of the detected radiation.

    Abstract: A device for measuring the properties of a fluid, a method of manufacture, and a method of operation is described. The device includes a body region, a first flexible element and a second flexible element. Each flexible element has a first end and a second end, the first end being fixedly located on the body region. Each flexible element is moveable from at least a first respective configuration to a second respective configuration via bending of the element. The first flexible element includes an actuating portion arranged to move the flexible element between the first configuration and the second configuration. The second flexible element includes an integral movement sensor for sensing movement of the flexible element. The first flexible element is coupled to the second flexible element at a position distant from the body region. Only the actuating portion of the first flexible element is operable to move the first and second flexible elements.

    Abstract: The terahertz camera has a fixed objective lens (2) and a plurality of detectors (3) positioned at the focal plane of the objective lens (2). Each of the detectors (3) is mounted on a movable support (10) so that the antenna is capable of movement across the focal plane of the objective lens (2) and is provided with a flexible waveguide (4) for connecting the output of the detector (3) with signal processing means. Each detector (3) is also provided with a retroreflector (6) which is reflective at frequencies other than terahertz frequencies. During use of the camera, the retroreflector (6) of each detector (3) is illuminated at non-terahertz frequencies so that the spatial position of each detector (3) and hence the spatial source of signals generated by the detector can be accurately identified. The terahertz camera is particularly suited for use in security installations and in chemical and food processing industries.
