Patent number: 7835002Abstract: Arrangement for the production of instantaneous or non-instantaneous multi-band images, to be transformed into multi- or hyperspectral images, comprising light collecting means, an image sensor array, and an instantaneous colour separating means, positioned before the image sensor array, and uniform spectral filters, for restricting imaging to certain parts of the electromagnetic spectrum. A filter unit is positioned before the colour separating means in the optical path in, or close to, converged light. Each filter mosaic consists of a multitude of homogeneous filtering regions. The transmission curves 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. The transmission curves of the colour or spectral filter mosaics and the colour separating means are suitably spread out in the intervals of a spectrum to be studied.Type: GrantFiled: October 25, 2005Date of Patent: November 16, 2010Assignee: RP Ventures Technology Office ABInventors: Hamed Hamid Muhammed, Fredrik Bergholm
