Sung-Chul Hohng has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9563046
    Abstract: A confocal fluorescence microscope of the present invention consists of: a light source unit broadly comprising one or more short wavelength laser beams; a lens unit which converts parallel light, emitted from a light source, into linear light having an appropriate size; a multi-color mirror which reflects the light source and enables fluorescence to transmit so as to separate the light source and the fluorescence; a scan mirror which radiates the light source over a wide area and scatters the fluorescence over a large-area camera; a microscope unit which radiates the incident light source to a target object, collects the fluorescence emitted from the target, and outputs the collected fluorescence; and a detecting unit which removes the background of the outputted fluorescent signal and observes the outputted fluorescent signal.
    Type: Grant

  • Patent number: 7359598
    Abstract: Disclosed is a surface plasmon optic device that has a periodic array of apertures in a dielectric substrate and a metal film formed on the dielectric substrate and emits light from metal-air interface. The surface plasmon optic device includes a surface plasmon generating apparatus, a surface plasmon detecting apparatus, a surface plasmon controlling apparatus, an etching apparatus, etc. if a metal diffraction grating is disposed on the metal film having a well-defined interface, propagation of the surface plasmon can be efficiently reflected, divided and controlled. Further, radiating surface plasmon having a half period of a lattice constant formed at air-metal (1, 0) can be preserved at a distance of at least a few micron.
