The invention discloses a far-field super-resolution visual imaging device and an imaging method. The visual imaging device comprises a super-resolution amplifier and an optical microscope. Based on a short wavelength effect of a metal surface plasma wave, the surface plasma wave has stronger space differentiating capability than a free space electromagnetic wave with the same frequency; by usingthe characteristic, a super-resolution amplifier with an amplifying function is obtained; and the space information of an observed thing is initially amplified and is further amplified by using an optical microscope to obtain a super-resolution imaging result. The invention overcomes a restriction of a diffraction limit of a traditional optical microscope system, and realizes far-field visual imaging differentiation of an object of which the spacing is less than a traditional optical microscope resolution.
