Abstract: A device includes capture sites; an imaging system for imaging the capture sites; a memory that stores a map of the capture sites including capture site shapes having respective predefined positions in the map and to be placed on an image of the capture sites, at a predefined position and in a predefined orientation so that the capture site shapes respectively indicate the areas of the image occupied by the capture sites; and a module for detecting an odor from an image of the capture sites and the map. The device includes an update module for obtaining an image of the capture sites, for determining, in the image, real areas respectively occupied by the capture sites, for determining, on the basis of the real areas, a correction of the position and/or of the orientation of the overlay of the map; and for updating the position and/or orientation of the overlay.

Abstract: An odor identification device includes capture sites designed to capture odorous volatile organic compounds present in an ambient air; an imaging system for imaging the capture sites designed to provide at least one raw image of the capture sites. The device further includes an unblurring module designed to implement an unblurring filter using an estimate of a spatial impulse response of the imaging system, on an image to be unblurred that originates from at least one raw image of the capture sites; and a module for identifying an odor from at least one image of the capture sites unblurred by the unblurring module.

Abstract: A photonic integrated circuit for an interferometric sensor includes a first waveguide called sensitive arm wherein a first portion of the light radiation is propagated, the sensitive arm being exposed to a first ambient medium and to at least one compound to be detected inducing a modification of the local refractive index perceived by the evanescent part of the electromagnetic field of the first portion of the light radiation, and a second waveguide called reference arm wherein a second portion of the light radiation is propagated, an encapsulation layer encapsulating the reference arm, the encapsulation layer being impermeable to the compound or compounds to be detected, so that the reference arm is exposed only to a second ambient medium, substantially of the same nature as the first ambient medium and without the compound to be detected and interferometric sensor comprising a photonic integrated circuit according to the invention.
