| 摘要 | A thin-film was proposed for optical super-resolution imaging, which substitute the liquid layer with a soft mold in the original dielectric microsphere based super-resolution imaging.The imaging character of silica and barium titanate glass microsphere immersed in three different liquid were investigated.And a thin-film was prepared which contains a layer of closely-arranged barium titanate glass microsphere embedded in a transparent polydimethylsiloxane soft mold.The result shows that the silica microsphere can discern the sample feature below the diffraction limit only it is semi-immersed in the liquid with refractive index lies in the range 1.33~1.548.However, the barium titanate glass microsphere should be fully immersed to achieve super-resolution imaging.The experiment is also taken to verify the feasibility of the thin-film based super-resolution imaging.A grating with period of 278 nm can be clearly discerned at the illuminated wavelength of 600 nm. ©, 2015, Chinese Optical Society.
