The invention pertains to a method for transforming a set of spectral images, the method comprising: dividing the images in said set in identically arranged areas; for each of said areas, calculating a predetermined characteristic across said set of images; and, for each of said images, renormalizing intensity values in each of said areas in function of said predetermined characteristic of said area. The invention also pertains to a corresponding computer program product and a corresponding image processing system.


Apparatus (30) for plasma processing of a continuous substrate (16), comprising a first plasma torch. The first plasma torch comprises a first electrode (11), a second electrode (12) arranged opposite the first electrode to define a first plasma discharge chamber (13) between the first and second electrodes. The first plasma discharge chamber (13) comprises an inlet (131) and an outlet (132) for passing a plasma forming gas (133) between the first and second electrodes. The apparatus further comprises an afterglow chamber (17) in fluid communication with the outlet (132) of the first plasma discharge chamber and a transport means for continuous transporting the substrate (16). The afterglow chamber (17) comprises a substrate inlet (172) and a substrate outlet (173) arranged at opposite sides of the outlet (132) of the first plasma discharge chamber (13). The transport means is configured to transport the substrate from the substrate inlet (172) to the substrate outlet (173) through the afterglow chamber (17) and such that the substrate is kept remote from the first plasma discharge chamber (13) while being processed by plasma activated species flowing from the outlet (132) of the first plasma discharge chamber into the afterglow chamber (17). The substrate inlet (172) comprises an aperture having a cross-sectional size (G1) substantially smaller than a cross-sectional size (G2) of the afterglow chamber (17) at the outlet (132) of the first plasma discharge chamber (13). The apparatus can further comprise a second plasma torch (32) aligned with and arranged opposite the first plasma torch (31), with the afterglow chamber (17) interposed between. The outlets (132, 232) of the first and second plasma torches face each other and exhaust plasma activated species into the afterglow chamber (17).


Apparatus for plasma processing of a continuous fiber, comprising a first and a second plasma torch. Each plasma torch comprises oppositely arranged electrodes to define a plasma discharge chamber between the electrodes. The plasma discharge chamber comprises an inlet and an outlet for passing a plasma forming gas between the electrodes. The apparatus further comprises an afterglow chamber in fluid communication with the outlets of the plasma discharge chambers, which comprises a substrate inlet and a substrate outlet arranged at opposite sides of the outlets of the plasma discharge chambers. A transport system is configured to continuously transport the fiber from the substrate inlet to the substrate outlet through the afterglow chamber. The substrate inlet comprises an aperture having a cross-sectional size substantially smaller than a cross-sectional size of the afterglow chamber. The outlets of the plasma torches face each other and exhaust plasma activated species into the afterglow chamber.
