Claim Text:
1. An optical imaging apparatus comprising: 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, wherein the light adjustment system comprises a spatial beam distributor, the spatial beam distributor including a plurality of beam distributor filters and configured to change a cross-sectional size and an incident path of the incident beam by passing the incident beam through at least one of the beam distributor filters.
