Abstract (en)
[origin: WO2019053364A1] The invention relates to a device for capturing a hyperspectral image (15), comprising: means for acquiring a diffracted image (14) of a focal plane; means for acquiring at least two non-diffracted images (17-18) of the focal plane, obtained with different chromatography filters (F1-F4); and means for constructing a hyperspectral image (15) from the different diffractions (R0-R7), comprising a neural network configured to calculate the intensity of each voxel of the hyperspectral image (15) according to: the light intensity in each of the non-diffracted images (17-18) at coordinates x and y, the weight of each intensity depending on the closeness of the desired wavelength to the colour of the chromatography filter of said non-diffracted image; and light intensities in each of the diffractions of the diffracted image (14) in which the x, y coordinates are dependent on coordinates x, y and λ of the voxel.
