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:
The invention concerns an optical imaging device for a human or animal body, including: an optical sensing system, a drive system of at least one light collector from the optical sensing system, permitting modification of at least the position and/or direction, and a control system from the drive system, arranged so as to lead the light collector from the optical sensing system to at least one observation situation of at least one chosen region of the body to be examined, based on data concerning its topology.
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.
