DE 102007050167 A1 UPAB: 20090514 NOVELTY - The array has micro lenses (9) arranged on, in or behind a side of a laminar optically transparent base body. A light source e.g. organic LED, is arranged at, in or on the body. Projection of the light source lies in a direction of optical axes of the lenses at the side of the body between the lenses. The light source includes polymer and small molecules. A diaphragm layer has a black-matrix polymer. A conductive transparent layer (2) is made of thin metal layers. The lenses and the body are made of plastic, thermosetting polymer and/or thermosetting inorganic-organic hybrid polymer. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (1) an imaging system for imaging an object in an object surface on an image in an image surface (2) an imaging method for imaging an object in an object surface on an image in an image surface (3) a method for manufacturing a micro-lens array (4) an image acquisition device. USE - Micro-lens array for use in an imaging system for imaging an object in an object surface on an image in an image surface, in an image acquisition device that is utilized in a surface plasmon resonance sensor and an optical personal computer mouse, as a fingerprint sensor, displacement sensor, navigation sensor, and optical coupler or switch for optical data transmission, for measuring bidirectional reflectance distribution function of a dispersive surface, for detailed and finely dispersed and laminar reception of a non-transparent planar object without optical magnification, and for laminar reception of a document, in an extreme short-structured incident light microscope for an object having a large surface (all claimed). ADVANTAGE - The array allows imaging of a laminar wide object without the need for moving an optical system relative to the object and an image sensor. The array eliminates the need for scanning the object, and allows manufacture of an imaging system and the optical system using less number of components, in a cost-effective manner. The array allows homogeneous illumination independent of scaling of the object and the optical system.
