Abstract: A device for scanning the surface of a sample which is covered with a liquid, comprising a probe which has a tip at one end, means for moving the probe and the sample relative to one another a light source focussing device which focuses light from the light source onto a location in the area of the tip located in the liquid and a detector for detecting light which was scattered by the tip, wherein a boundary surface at which the light enters the liquid is located on the light path between the light source and the tip, wherein the boundary surface is positionally fixed with respect to the probe.

Abstract: The present invention discloses a method for the intercalation of a chromophore within channels of a zeolite L crystal. The intercalated chromophores exhibit J type aggregation of the chromophores within the channels of the zeolite L crystals. The invention discloses method parameters which lead to the J type aggregation of the chromophores within the channels of the zeolite L crystals. The J type aggregation of the chromophores affords unique florescent properties rendering the intercalated zeolite L crystals as a material for use in novel optoelectronic devices.

Abstract: In a method for monoscopically representing at least one image area of an image on an autostereoscopic display apparatus with a resolution of M×N arranged like a matrix with M columns and N rows and a plurality of active or passive beam splitters or parallax barriers that separate the monitor pixels in P fields, an image area that is to be represented monoscopically is selected. A representation of the selected area is generated with a resolution of M/S×N/K image pixels wherein 1<S?P and 1<K?P and wherein each image pixel has assigned thereto a pixel value that on the display apparatus can be represented in color or black/white. The representation is transformed to the resolution M×N of the display apparatus and the transformed representation is read out into the display apparatus.
