    摘要： The invention relates to an apparatus for reversible optical data storage using polymeric liquid crystals with mesogenic side groups as a storage medium, arranged to store information by means of selective variation of the order of the polymeric liquid crystals be means of a heat source. The macroscopically oriented film made from the liquid crystal polymer is held in the solid form retaining condition of the liquid crystal polymer in the temperature range below the glass temperature T.sub.g >T.sub.a (room remperature) for the purpose of storing the information. The polymer is then selectively and locally heated by means of the heat source into the isotropic liquid condition and the local information is fixed in the glass condition of the polymer after the heat source is turned off.

    摘要： A process for identifying an embossed image of a coin in an automatic coin tester, in which a coin is moved to an image receiver and a light source, the image receiver picks up at least one image of the embossed image of the coin, and a validation device compares the image to a first reference pattern to find out whether the first reference pattern is contained in the image which was picked-up. If the first reference pattern is contained in the image, the validation device determines whether a second reference pattern is contained in an area the position of which is determined relative to the position of the first reference pattern, the validation device producing a genuine coin or counterfeit coin signal for the coin depending on the coincidence of the image with the reference patterns.

    摘要： To identify an embossed image of a coin in an automatic coin machine, the coin requiring identification is moved past an image receiver and a light source, the light source having at least two lighting portions which illuminate an object field of the coin requiring identification from different directions under the same angle with respect to the surface normal of the object field and with wavelength ranges which do not overlap each other. An image receiver records one picked-up exposure of the object field from which images are obtained for each of the individual lighting portions of the individual wavelength ranges. A maximum image is then determined from the images, wherein each pixel has associated therewith the maximal intensity value from the images of the individual wavelength ranges. A genuine-coin or counterfeit-coin signal is determined from the maximum image.

    摘要： A method for mechanically stabilizing and for tuning a filter having a photonic crystal structureThe cavities of the filter fabricated as a photonic crystal structure are filled with optically transparent material having an adjustable refractive index. The optical properties of the filter and, thus, the filtering action are adjusted by way of an electric field having a variable field strength.It is possible to produce small-dimensioned, narrow-band filter elements, which are finely tunable and tunable within a broad range, and to realize them as filter elements which are integrated with a high packaging density.
