  • Publication number: 20150041680
    Abstract: Disclosed is an optical imaging system having improved resolution. The disclosed optical imaging system may include a substrate on which a specimen dyed with a fluorescent material is placed; a multiple number of dimer nanopillars formed on the substrate; and a light source unit configured to provide a light source to the substrate, where the light source unit provides an incident ray to the substrate from a first light source to excite the fluorescent material, and afterwards turns off the first light source and activates a second light source and a third light source simultaneously to provide incident rays to the substrate. The disclosed optical imaging system can provide a resolution that is higher than the diffraction limit.

  • Patent number: 7583768
    Abstract: We provide an ISI canceling circuit including a storing unit to store an ISI value associated with a received signal, an operator to generate an operator output signal by subtracting the ISI value from the received signal, and a comparator to manipulate the operator output signal responsive to an operating mode. We also provide a method for canceling ISI that includes storing a base voltage value of the received signal, sequentially storing ISI values of the received signal at time points when ISI is desired to be canceled, generating a difference between each of the stored ISI values and the stored base voltage value, and amplifying the subtracted signal to determine its logic state.
