Abstract: A method of limiting cross-talk in an imaging sensor, the sensor being in the form of a matrix of macropixels defining an image, each macropixel being formed by a matrix of individual pixels, each of which is dedicated to a distinct spectral band, all of the individual pixels dedicated to the same spectral band forming a sub-image, the image being topologically subdivided into at least one parcel, and the method including the following steps: measuring the spectral response of each individual pixel λ1, λ2, λ3, . . . , λ9; calculating the mean spectral response of each sub-image in a parcel; targeting to define the ideal response of each sub-image in the parcel; estimating a series of coefficients for minimizing cross-talk in the parcel; and applying the coefficients to the macropixels in order to correct the sub-images in the parcel. The method is remarkable in that the ideal response is a Gaussian function.

Abstract: The invention relates to a wavelength spectroscopy device comprising, on a substrate SUB, a filter module made up of two mirrors MIR1, MIR2 that are spaced apart by a spacer membrane SP. The filter module comprises a plurality of interference filters FP1, FP2, FP3, the thickness of said spacer membrane SP being constant for any given filter and varying from one filter to another.
