  • Patent number: 9589227
    Abstract: The present invention relates to a method and a corresponding apparatus for identifying a product (1) or information relating to the product (1). In the method, a concealed code on the product (1) is identified, wherein the code is given by a set of ellipsometric parameters, and the method comprises the following steps of: measuring ellipsometric variables for at least one defined point (8) on a surface (9) of the product (1), comparing the measured ellipsometric variables with at least one reference code, and determining a match between the measured ellipsometric variables and the reference code or one of the reference codes or determining a mismatch with each reference code.

  • Publication number: 20070159629
    Abstract: A method for analyzing organic adsorbent layers (7) on a substrate (4) comprises the steps of providing a substrate (4) whose surface has an index of refraction equal or close to the index of refraction of the organic adsorbent to be analyzed. On the surface of the substrate (4) there is applied a layer system (5,6) with at least one layer (5) with index of refraction of the biological material and an organic adsorbent layer (7) on top of the layer system. When acting polarized light upon the substrate a change of polarization characteristics in reflection and/or transmission is detected.

  • Publication number: 20050200846
    Abstract: Image producing ellipsometric measuring process, in which a plurality of individual images, which respectively represent at least one part of an object, are sequentially recorded by means of an image producing detector with varying ellipsometrically relevant recording parameters (102, 108), are stored at least temporarily in a digital memory, and are at least sectionally combined with each other by computation according to pre-set rules for production of an output image or value (126), thereby characterized, that in a reference image a region of interest (ROI) is defined on the basis of image information parameters and its position and/or shape in a first individual image is determined (104), in a second individual image the position and/or shape of the ROI is determined (112) on the basis of the same image information parameters, the second individual image is corrected (122) by translation, rotation, compression and/or stretching at least sectionally in the manner, that the position and/or shape of the
