    摘要： A picture display device comprising a cathode ray tube (1) with an elongated display screen (8) and a deflection system (9) is described. The deflection power is reduced by two means. The deflection system (9) is arranged to scan the lines in the direction of the short axis (22) of the display screen (8), and the cone portion (3) of the cathode ray tube (1) has an elongated cross-section (54) whose aspect ratio is larger than or equal to the aspect ratio of the display screen (8), thereby enabling the deflection system (9), and in particular the line deflection subsystem (12), to be positioned closer to the electron beam envelope (51), which reduces magnetic losses.

    摘要： An optical arrangement of at least a coherent light source (1), a strongly scattering object (5) (the PUF), and a pixe-lated photo-detector (6), wherein the pixels are comparable in size with the bright and dark patches of the speckle pattern produced by coherent radiation traversing the scattering object (5). Quantitively, the pixel size should be roughly λ/NA, where λ is the wave-length, and (i) NA=a/z for free-space geometry, with a being the beam radius and z being the distance between the exit surface of the PUF (5) and the pixelated detector (6), or (ii) NA is the numerical aperture of a lens (7) in an imaging geometry. In a preferred embodiment of the invention, there are tentative requirements that the pixels should be at least smaller than ηmaxλNA and preferably larger than ηmaxλ/NA, where (in an exemplary embodiment) ηmax=5 and ηmin=0.05, say. It will be understood by a person skilled in the art that the present invention is concerned with the optical arrangement of the PUF (5) and the photo-detector (6), rather than the photo -detector (6) per se.

    摘要： The present invention relates to a method and a device (11) using a physical token (14), which provides measurable parameters, to derive at least one data set. A plurality of values of one or more of the parameters are measured. From these measured values, a measure of variance is calculated. Quantization intervals into which a measured value is to be quantized are then determined. A possible value of a data set, which subsequently can be derived from a measured value provided by the physical token, is associated with each quantization interval. Further, information which subsequently enables determination of these quantization intervals is stored. Hence, an enrolling phase has been completed. When the preparing phase has been completed, a deriving phase may commence. When a data set is to be derived, for example to be used as a cryptographic key, a value of any one of the parameters provided by the PUF is measured. This measured value is quantized into a determined quantization interval, and a data set may be derived from the quantization interval into which the measured value is quantized.
