Patent ID: 8664583

Claim:
A system for nonlinear electromagnetic surface sensing, the system comprising: at least two signal sources that are co-aligned to propagate photons to a same location on a surface to be reflected off of the surface; at least one focusing element that focuses a sequence of photons that is reflected from the same location on the surface; at least one nanoparticle-sized diameter thermoelectric junction, of at least one frequency selective electromagnetic detector, that detects the sequence of photons that are focused from the at least one focusing element, wherein when the at least one nanoparticle-sized diameter thermoelectric junction senses at least one photon, the at least one nanoparticle-sized diameter thermoelectric junction emits at least one electrical pulse having a voltage that is proportional to an energy level related to a wavelength of the at least one photon; and at least one processor that processes the at least one electrical pulse and de-multiplexes a sequence of the at least one electrical pulse based on the at least one electrical pulse voltage.
