  • Super-resolved optical imaging apparatus and optical imaging method using the same
    Patent number: 9383319
    Abstract: A super-resolved optical imaging apparatus and a super-resolved optical imaging method using the apparatus are disclosed. The optical imaging apparatus can includes: a light source unit configured to supply an incident beam; a nano-pattern chip having a plurality of nanostructures; a light adjustment system configured to change an incidence property of the incident beam in at least one of a horizontal direction and a depth direction such that surface plasmon resonance occurs in a localized area of the plurality of nanostructures; and an image detection unit configured to extract fluorescence signals generated by the surface plasmon resonance from a specimen positioned in the localized area and convert the fluorescence signals into an image.
    Type: Grant
