Abstract: Method for viewing a laser spot included in a multispectral image representing an optical field composed of pixels including a plurality of components, the laser spot being produced by a laser pointer and having a wavelength taking values in a range of wavelengths dependent on operating temperatures of the laser pointer. The method includes: obtaining a multispectral image in which each component corresponds to the same instant of acquisition and represents a spectral band in a plurality of spectral bands covering continuously a spectral domain comprising said range of wavelengths; applying a contrast-accentuation procedure to a subpart of the multispectral image comprising the laser spot in order to obtain a subpart in which a contrast between the laser spot and a background is improved; and generating an image allowing display of the laser spot using information obtained following the application of said procedure.

Abstract: The invention relates to a method for analyzing a multispectral image (10), which includes designing a detection image from the values of a revealing function that quantifies a content shift in the multispectral image between two areas. The revealing function is applied between a target area and a background area, inside a window which is determined around each pixel. The revealing function values are determined from integral images of order one, and optionally also of order two, which in turn are calculated only once initially, so that the total amount of calculations is reduced. The analysis method is compatible with a real-time implementation during a capture of consecutive multispectral images which form a video stream, in particular for an environment-monitoring task.

Abstract: The invention relates to a method for analyzing a multispectral image (10), which includes designing a detection image from signal-to-noise ratio values. The signal-to-noise ratio values relate to the content of the multispectral image inside a window which is determined around each pixel, when the contrast in the window is maximized by a Fischer projection. The signal-to-noise ratio values at calculated from integral images of order one and two, which in turn are calculated only once initially, so that the total amount of calculations is reduced. The analysis method is compatible with a real-time implementation during a capture of consecutive multispectral images which form a video stream, in particular for an environment-monitoring task.

Abstract: The inventive method for viewing of a multi-spectral image by an operator uses contrast optimization by Fisher projection. The Fisher projection is determined and applied within a window (F1, F2, F3, . . . ) that is smaller than a display screen matrix (1) used by the operator. The window is moved for successive updates of a depiction of the image that is displayed, while creating a remanence of the positions of the earlier windows and elements that were exposed in some of said earlier windows. The implementation of the method is particularly simple and intuitive for the operator, so as to improve the reliability and effectiveness of his or her monitoring.

Abstract: A method is disclosed to measure the permeability of films or coatings towards solvents (e.g. water). First a substrate comprising an absorption or container layer is provided, preferably the material is a porous material. To study water permeability, the porous material is hydrophilic or is made hydrophilic by means of e.g. an anneal process. To study the permeability of the film or coating, the coating is deposited on top of the porous material. The substrate comprising the film or coating on top of the absorption or container layer is then brought into a pressurizable chamber subsequently filled with the gaseous substance of the solvent (e.g. water vapor). By increasing/decreasing the vapor pressure in the chamber between zero and the equilibrium vapor pressure of the solvent used, the permeability (penetration) of solvent through the film or coating can be determined. The amount of solvent that can penetrate through the film or coating can be measured by means of ellipsometry, mass spectrometry, etc.
