    • The present invention relates to the production of instantaneous or non-instantaneous multi-band images, to be transformed into multi- or hyperspectral images, comprising light collecting means (11), an image sensor (12) with at least one two dimensional sensor array (121), and an instantaneous colour separating means (123), positioned before the image sensor array (121) in the optical path (OP) of the arrangement (1), and first uniform spectral filters (13) in the optical path (OP), with the purpose of restricting imaging to certain parts of the electromagnetic spectrum. The present invention specifically teaches that a filter unit (FU) comprising colour or spectral filter mosaics and/or uniform colour or spectral filters mounted on filter wheels (114) or displayed by transmissive displays (115), is either permanently or interchangeably positioned before the colour separating means (123) in the optical path (OP) in, or close to, converged light (B). Each colour or spectral filter mosaic consists of a multitude of homogeneous filtering regions. The transmission curves (TC) of the filtering regions of a colour or spectral filter mosaic can be partly overlapping, in addition to overlap between these transmission curves and those belonging to the filtering regions of the colour separating means (123). The transmission curves (TC) of the colour or spectral filter mosaics and the colour separating means (123) are suitably spread out in the intervals of a spectrum to be studied. The combination of the colour separating means (123) and the spectral or colour or spectral filter mosaics produces different sets of linearly independent transmission curves (TC). The multiple-filter image captured by the image sensor (12) is demosaicked by identifying and segmenting the image regions that are affected by the regions of the multiple filter mosaic, and after an optional interpolation step, a multi-band image is obtained. The resulting multi-band image is transformed into a multi- or hyperspectral image.
    • 本发明涉及要转换成多光谱或高光谱图像的瞬时或非瞬时多频带图像的制作,包括光收集装置(11),具有至少一个二维传感器阵列的图像传感器(12) (121),以及位于所述装置(1)的光路(OP)中的图像传感器阵列(121)之前的瞬时颜色分离装置(123)和光路中的第一均匀光谱滤光器(13) OP),目的是将成像限制在电磁谱的某些部分。 本发明具体指出,安装在滤光轮(114)上或由透射显示器(115)显示的颜色或光谱滤光器马赛克和/或均匀颜色或光谱滤光器的滤光单元(FU)可以永久地或互换地定位在 在光路(OP)中或接近于会聚光(B)的颜色分离装置(123)。 每个颜色或光谱滤波器马赛克由多个均匀的滤波区组成。 除了这些传输曲线与属于分色装置(123)的滤色区域的那些之间的重叠之外,颜色或频谱滤波器马赛克的滤波区域的传输曲线(TC)可以部分重叠。 颜色或光谱滤光器马赛克的传输曲线(TC)和颜色分离装置(123)适当地在待研究的光谱的间隔中展开。 颜色分离装置(123)和光谱或颜色或光谱滤波器马赛克的组合产生不同的线性无关的传输曲线(TC)组。 由图像传感器(12)捕获的多重滤波器图像通过识别和分割受多重滤波器马赛克的区域影响的图像区域进行去马赛克,并且在可选的插值步骤之后,获得多波段图像。 所得到的多频带图像被转换为​​多光谱或高光谱图像。

    • The invention is a method for obtaining a reactive sputtering process with a reduced or eliminated hysteresis behaviour. This is achieved by focusing the ion current onto a small area, a reduced erosion area (14), which is in constant motion along the target (10) to avoid melting of target material. This means that the current density is very high at the reduced erosion area (14) while the average overall current density is significantly lower. The problem with arcing during reactive sputtering will be suppressed since the compound layer is effectively removed if the current density is sufficiently high. Moreover, the high current density results in a substantial increase of the fraction of ionized sputtered species.
    • 本发明是用于获得具有减小或消除的滞后行为的反应溅射工艺的方法。 这是通过将离子电流聚焦到小的区域,减小的侵蚀区域(14)来实现的,该侵蚀区域沿靶材(10)恒定运动以避免目标材料的熔化。 这意味着在减少的侵蚀面积(14)下,电流密度非常高,而平均总电流密度显着降低。 如果电流密度足够高,则化合物层被有效地去除,反应溅射期间电弧的问题将被抑制。 此外,高电流密度导致电离溅射物质的分数显着增加。
