Patent ID: 8767207

Claim:
A system for optical detection of particles arranged in a viewing area suitable for being illuminated by radiation with a predetermined wavelength, said system comprising optical detector, and an assembly of metal plasmonic channels arranged in a single plane of which one end is proximate to the viewing area to allow optical information resulting from the illumination of the particles arranged in the viewing area to be transferred from one end to the other of said channels, said channels being arranged so that said assembly forms around the viewing area an array for transferring said optical information, the value of at least one spatial characteristic of said array being lower than said wavelength at the ends of said channels proximate to said viewing area, the value of at least one spatial characteristic of said array space being higher than said wavelength at the ends of said channels distant from said viewing area, said system further comprising an optical decoupler between said ends distant from said viewing area and said optical detector, the optical decoupler configured to decouple the optical information being transferred to the ends of said channels distant from said viewing area to usable light for imaging, the usable light for imaging being collected by the optical detector in order to perform the optical detection of the particles being arranged in the viewing area.
