  • Publication number: 20110171320
    Abstract: In a method for visualizing an object under conditions of low ambient light, the object to be visualized is exposed to incident electromagnetic radiation having a wavelength greater than what can normally be seen by the naked eye. Light reflected from the object is then perceived with an enhanced eye. The enhanced eye contains an up-conversion material optically coupled to the photoreceptors. Up-conversion materials absorb in the infrared and luminesce in the visible. Particles containing such materials are delivered to the eye where they are optically coupled to the retina or photoreceptor cells and nearby tissues. There they provide in-situ up-conversion of infrared frequencies (from about 700 to about 11,000 nm) to the otherwise unaided eye.

  • Publication number: 20090207869
    Abstract: The present invention can selectively control surface plasmon-mediated two-photon-induced luminescence in a dendritic silver nanoparticle system over distances of up to 100 m. This control is achievable by changing the polarization of the incident beam and by controlling the phase across the spectrum of a femtosecond laser pulse used for excitation. Furthermore, the present invention uses the phase and polarization dependence to address photonically locations within substantially 100 m from the focal spot.
