  • Publication number: 20140198198
    Abstract: The invention describes a method and a microscopy system for imaging and analysing stochastically and independently blinking point-like emitters. A multiple-order cumulants analysis in conjunction with an established blinking model enables the extraction of super-resolved environment-related parameter maps, such as molecular state lifetimes, concentration and brightness distributions of the emitter. In addition, such parameter maps can be used to compensate for the non-linear brightness and blinking response of higher-order cumulant images—used for example in Super-resolution Optical Fluctuation Imaging (SOFI)—to generate a balanced image contrast. Structures that otherwise would be masked by brighter regions in the conventional cumulant image become samples using spectral cross-cumulants.

  • Publication number: 20140168426
    Abstract: A method and computing system are proposed for producing an authenticable security device with two sides. The verso side is covered with an adjustable luminescent emissive layer formed by invisible luminescent ink halftones and possibly a UV absorbing printed layer. The recto side is covered with transmissive non-luminescent ink halftones. The backlit colors resulting from the emissions of the luminescent layer or resulting from illumination by normal white light through the transmissive non-luminescent ink halftones are predicted by a backlighting model. This model enables computing the surface coverages of the luminescent and/or non-luminescent ink halftones in order to obtain a desired color either under excitation light (UV light) or under normal white light. This enable creating authenticable backlit images substantially similar to pre-stored reference images, either under normal white light, under excitation light, or under both the normal white light and the excitation light.
