Abstract: A method of making a high resolution camera includes assembling, imaging and processing. The assembling includes assembling on a carrier a plurality of sensors. Each sensor is for imaging a portion of an object. The plurality of sensors are disposed so that the portions imaged by adjacent sensors overlap in a seam leaving no gaps between portions. The imaging images a predetermined known pattern to produce from the plurality of sensors a corresponding plurality of image data sets. The processing processes the plurality of image data sets to determine offset and rotation parameters for each sensor by exploiting overlapping seams.

Abstract: A method of making a high resolution wide format sensor for imaging a moving image conjugate includes assembling, imaging and processing. Plural sensors are assembled on a carrier. Each sensor images a strip portion of the moving image conjugate. The plural sensors are disposed so that strip portions imaged by adjacent sensors overlap in a seam leaving no gaps between strip portions. The carrier and the sensors have been fabricated out of materials with compatible coefficients of thermal expansion. A known pattern is imaged to produce from the sensors corresponding plural strip image data. The strip image data are processed to determine offset and rotation parameters for each sensor by exploiting overlapping seams.

Abstract: A method for in a multi-pixel pick-up element reducing a pixel-based resolution and/or effecting anti-aliasing through selectively combining selective primary pixel outputs to combined secondary pixel outputs, comprises the following steps: row-wise, whether or not restrictively, selecting pixels for loading into a first parallel-in register; serial shifting of the load within the register for aligning selected first pixels in the first parallel-in register with selected second pixels not in the first parallel-in register; arithmetically combining pixel groups so aligned; and outputting combination results from preselected multi-pixel configurations as secondary pixels. The invention is applicable to a selection from amongst a two-dimensional pick-up array, an Interline Architecture, a Frame Transfer Architecture, a combination of those two, a TDI pick-up array, and a linear pick-up array, and for both mono-color and multi-color pick-up facilities.

Abstract: The optical component comprises a first element (1) having a light-emission surface (2) and a second element (3) having a light-entrance surface (4), a bonding layer (5) interconnecting the elements (1, 3) being provided between said surfaces (2, 4). The bonding layer (5) is an optically transparent layer of paraffin, which efficiently couples light from the first element (1) into the second element (3) and carefully positions said elements (1, 3) with respect to each other. In the method of manufacturing the optical component, the first element (1) and the second element (3) are fitted together by joining the surfaces (2, 4) so as to form a capillary space (7), which capillary space (7) is filled by making it suck up liquid paraffin, the paraffin is allowed to cool and solidified in order to form an optically transparent bonding layer (5) of paraffin in the capillary space (7).

Abstract: A description is given of an optical switching device (1) comprising a transparent substrate (3), a switching film (5) of a hydride compound of a trivalent transition or rare earth metal having a thickness of 300 nm, and a palladium capping layer (7) having a thickness of 30 nm. The capping layer is in contact with hydrogen. An electric current through the switching film (5) can be switched on and off between the terminals (9, 11). Joule heating of the switching film (5) causes a rapid transition from the transparent trihydride state to the absorbing dihydride state. By switching off the current, the switching film (5) cools down, which results in the formation of the absorbing dihydride state. The conversion between both states is reversible and can be repeated many times. The device can be used for controlling light beams, or it can be used in or for a display. Optionally, cooling of the switching film (5) is obtained with a Peltier element in thermal contact with the switching film (5).
