Abstract
A near field optical imaging device includes: a light source for radiating light of a far field optical system; and an optical head including thin film layer for formation of dynamic optical nano apertures, combined with a measured object in one piece to generate a near field by a beam radiated from the light source, in which the measured object can be scanned in a depth direction by adjusting a depth of the near field, and the depth of the near field is adjusted by modifying a shape of an opening of the thin film layer for formation of dynamic optical nano apertures by adjusting an amount of the light radiated from the light source.
