摘要:
A method for generating a unique identity for objects having measurable properties. The teachings include deriving unique features of the object and using them to generate a fingerprint for the device. The teachings also include techniques for providing appropriate signal processing for the incoming information from any physical device to be fingerprinted. The invention also includes methods for access control to optical recording media and physical devices.
摘要:
An optical sensing method with optical excitation in the ultraviolet (UV) range (200-400 nm wavelength) where biomolecules, which have inherent absorption lines in the UV range, adsorb on a plasmonic surface exhibiting coincident optical resonances in the UV, and the amplitude of the reflected/scattered/transmitted optical wave, which is strongly changed due to the presence of biomacromolecules or biomolecular structures, are measured or imaged to infer the presence and optical properties of the adsorbed biomolecular structures.
摘要:
Plasmon-integrated sensing mechanism comprised of three fundamental parts: a grating structure (2) with a specific metalization thickness (1) for the coupling of photons with the surface plasmons; a fluidic channel structure (4) in which liquid solutions with different refractive indexes will be streamed; and a photo-sensitive substrate (3) that can detect the light (8) which encounters changes in its intensity as the result of excitation of surface plasmons. The photo-sensitive substrate (3) may work according to photo-diode principle or it may work according to plasmon-assisted photo-resistor principle by using thin film amorphous carbon which exhibits resistance change sensitive to temperature.
