Abstract: Filtering matrix structure comprising at least three color filters and a plurality of near Infrared filters, each one of the color filters and the near Infrared filters having an optimum transmission frequency, wherein the filtering matrix structure is made of n metal layers (m1, m2, m3) and n substantially transparent layers (d1, d2, d3) which alternate between a first metal layer (m1) and an nth substantially transparent layer (d3), each of the n metal layers (m1, m2, m3) having a constant thickness and at least one substantially transparent layer having a variable thickness which sets the optimum transmission frequency of each color filter and each near Infrared filter, n being an integer larger than or equal to 2. Application to 3D mapping and imaging.

Abstract: A device for interference spectroscopic analysis of radiation is of the interference type. The device includes at least a first reflecting layer onto which is deposited a multilayer of alternately transparent and photo-absorbing films. Each photo-absorbing layer is connected to an electronic detection unit supplying a primary electronic signal. The device also includes an electronic analyzing unit for analyzing the primary signals and configured in such a manner as to determine the spectral distribution of the original radiation.
