    摘要: A method for laser beam machining of a workpiece in which a laser beam is focused by an objective, into or onto the workpiece having a boundary surface, to produce a machining effect by a two-photon process, and the position of the focal point with respect to the workpiece is shifted. To obtain a reference for the position of the focal point, an image of a luminating modulation object is projected through the objective onto the workpiece into the focal plane or so as to intersect it. Reflections of the image occurring at the boundary surface are imaged into an autofocus image plane, and are detected by a camera. The camera image plane either intersects the autofocus image plane when the image of the illuminating modulation object lies in the focal plane, or lies in the autofocus image plane when the image of the modulation object intersects the focal plane.

    摘要: A method and arrangement for collimated microscopic imaging, including a first illumination of a sample in at least one region for exciting fluorescence, and a spatially resolving detection of the sample light by detector elements, the detection being associated with the region, wherein by means of a second illumination a sub-division of the region into separate fluorescent partial regions occurs, which are associated with the detector elements. The separation of the partial regions is carried out by the spatial separation of the fluorescent regions by means of intermediate regions having reduced fluorescence or no fluorescence, and/or by means of different spectral properties of the fluorescence from the partial regions.

    摘要: An improved confocal microscope system is provided which images sections of tissue utilizing heterodyne detection. The system has a synthesized light source for producing a single beam of light of multiple, different wavelengths using multiple laser sources. The beam from the synthesized light source is split into an imaging beam and a reference beam. The phase of the reference beam is then modulated, while confocal optics scan and focus the imaging beam below the surface of the tissue and collect from the tissue returned light of the imaging beam. The returned light of the imaging beam and the modulated reference beam are combined into a return beam, such that they spatially overlap and interact to produce heterodyne components. The return beam is detected by a photodetector which converts the amplitude of the return beam into electrical signals in accordance with the heterodyne components. The signals are demodulated and processed to produce an image of the tissue section on a display. The system enables the numerical aperture of the confocal optics to be reduced without degrading the performance of the system.

    摘要: An electro-optically active polymer gel material comprising a high molecular weight alignment polymer adapted to be homogeneously dispersed throughout a liquid crystal to control the alignment of the liquid crystal molecules and/or confer mechanical stability is provided. The electro-optically active polymer gel comprises a homogenous gel in which the polymer strands of the gel are provided in low concentration and are well solvated by the small molecule liquid crystal without producing unacceptable slowing of its electrooptic response. During formation of the gel, a desired orientation is locked into the gel by physical or chemical cross-linking of the polymer chains. The electro-optically active polymer is then utilized to direct the orientation in the liquid crystal gel in the “field off” state of a liquid crystal display. The electro-optically active polymer also provides a memory of the mesostructural arrangement of the liquid crystal and acts to suppress the formation of large scale deviations, such as, for example, fan-type defects in a FLC when subjected to a mechanical shock. A method of making an electro-optically active polymer gel material and an electrooptic device utilizing the electro-optically active polymer gel of the present invention is also provided.
