SPATIALLY RESOLVED GAS DETECTION |
摘要 |
The invention pertains to a method of spatially resolved detection of a gas substance in an area, comprising: imaging the area on a first image sensor, in a wavelength spectrum including an absorption wavelength peak corresponding to said gas substance; imaging the area on a second image sensor, to provide for each pixel of the first image a corresponding pixel of the second image for respective on- and off-peak wavelengths relative to the absorption wavelength; and providing a difference image as a function of the two pixel values of first and second image sensors to produce an image of the spatially resolved absorption wavelength corresponding to said gas substance. |
