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 (m, m, m) and n substantially transparent layers (d, d, d) which alternate between a first metal layer (m) and an nsubstantially transparent layer (d), each of the n metal layers (m, m, m) 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.
