摘要： An optically detectable marker comprising a matrix material, which is doped with a plurality of individual luminescent dopants and comprising at least a first luminescent dopant and a second luminescent dopant is described. The first luminescent dopant comprises a first unique absorption band such that the first luminescent dopant may be excited by illumination of a first wavelength, and wherein the first luminescent dopant is distributed in the matrix material so as to form a first spatial pattern in the matrix material, which first spatial pattern may be optically detected by illuminating the optically detectable marker by a light source illuminating light of the first wavelength. The second luminescent dopant comprises a second unique absorption band such that the second luminescent dopant may be excited by illumination of a second wavelength, different from the first wavelength, and wherein the second luminescent dopant is distributed in the matrix material so as to form a second spatial pattern in the matrix material, which second spatial pattern may be optically detected by illuminating the optically detectable marker by a light source illuminating light of the second wavelength.

摘要： An optical detection device for validating bank rates has several input apertures, an imaging device (12), a diffraction grating (15.1, 15.2, 15.3) associated with each input aperture (11.1, 11.2, 11.3) and a detection array (17). The diffraction grating (15.1, 15.2, 15.3) is rotated at angle of e.g.45 degrees relative to the orientation of the linear detection array (17). This arrangement enables the spectra of multiple points to be measured simultaneously. The angle of rotation, the pitch of the apertures (11.1, 11.2, 11.3) and a pitch of the diffraction grating (15.1, 15.2, 15,3) are selected in such a way that the spectra of sad multiple points are contiguously mapped onto the detection array (17) has a single linear array of color sensitive detection pixels. The acxis of the linear array is offset with respect to an optical axis (7) of the optical detection device.

摘要： Method for quick, automatic authentification of documents which are protected with optical features, wherein the positions of the features in relation to the coordinate system of the document and/or automatic testing machine are unknown or only known in an approximate manner. According to the invention, the document is either entirely or partially illuminated with an illuminating means in a first working phase, whereby the spectral and geometric distribution, degree of polarization and/or alignment, coherence and temporal activity are selected in such a way that one or more images arise for the illuminated end surfaces which can be detected by one or more imaging sensors, wherein the position of the security features form a difference in relation to the rest of the background of the document, so that said positions are automatically determined by means of the image recognition method in relation to the coordinate system of the document. In a second working phase, the corresponding features are only verified in the image areas corresponding to the positions found in the first working phase and the corresponding picture areas are illuminated. The corresponding features of the image generate spectral signatures and/or other optical patterns, wherefrom the information required for verification of the features can be derived using image processing methods and spectrometry.

摘要： The present invention relates to microparticle compositions comprising an organic IR absorbing pigment having a main absorption maximum in the range from 750 to 1100 nm. The invention also relates to a process for producing said microparticle compositions and to their use in a printing ink, in particular in a printing ink, which is suitable for producing a security feature or a security document. The microparticles of the pigment composition contain the organic IR absorbing pigment as solid particles, which are surrounded by or embedded in an aminoplast polymer, which is a polycondensation product of one or more amino compounds and one or more aldehydes. The microparticle based pigment composition is characterized by a volume based particle size distribution, as determined by static light scattering according to ISO 13320:2009 EN, having a D(4,3) value in the range from 1.0 to 15.0 µm.
