Patent ID: 8416283

Claim:
An imaging device comprising a photo-detector matrix, characterized in that it comprises: a first layer of material fixed on a face of the photo-detector matrix, the first layer of material being capable of reflecting or absorbing a light incident upon any one of its faces, an opening being formed in the first layer of material at each photo-detector; a second layer of material, made of an electrically insulating material, having a first face fixed on the first layer of material, the second layer of material surrounding, in the body thereof, a set of G waveguides, G being a whole number greater than or equal to 2, each waveguide of the set of G waveguides having a first end substantially flush with the first face of the second layer of material and being positioned substantially facing an opening and a second end substantially flush with a second face of the second layer of material opposite the first face, each second end forming a sensor element for a light incident upon the second face of the second layer of material, the distances that separate the first ends from the second ends of N distinct waveguides, N being a whole number greater than or equal to 2 and less than or equal to G, being different from each other; and the device is a 3D imaging device.
