Abstract: The invention relates to a method and a device for determining at least one mechanical property of at least one object, wherein the at least one object is subjected to at least one interaction which influences a movement state of the at least one object, wherein the at least one interaction is selected such that the movement state effectuated by the interaction is a function of the at least one mechanical property, wherein the at least one object is observed using at least one camera, wherein the movement state is determined from images recorded by the at least one camera and wherein the at least one mechanical property of the at least one object is determined from the movement state thus determined.

Abstract: The invention describes a multi-aperture device for detecting an object region having at least two optical channels for detecting a first sub-region of the object region and at least two optical channels for detecting a second sub-region of the object region. The optical channels for detecting the first and second sub-regions are arranged in an interlaced manner in a one-row structure, wherein the first and second sub-regions overlap at least partly.

Abstract: Method for structuring a device layer of a substrate, wherein the substrate includes a carrier layer, the device layer and an intermediate layer disposed between the carrier layer and the device layer. Thereby, the intermediate layer is structured for exposing, at least in one portion, a first surface of the carrier layer facing the device layer. Starting from a second surface of the carrier layer opposing the first surface, the thickness of the device layer is reduced to a predetermined thickness at those positions where the intermediate layer is removed.

Abstract: In a process for the fabrication of a radiation-absorbing optical element that contains a substrate (1) of plastic, a layer with a graduated refractive index (4) is fabricated on at least one surface (2) of the substrate (1) using a plasma etching process, after which a metal layer (7) is applied on top of the layer with a graduated refractive index (4).

Abstract: The present invention relates to a novel method for applying conductive structures on solar cells, a hot melt aerosol ink being atomised by means of an aerosol jet printing system and being discharged from the printing system in the direction of the solar cell, the printing system being heated at least partially in order to keep low the viscosity of the ink which is used. When impinging on the non-heated substrate (solar cell), the ink solidifies.
