The invention provides a super-resolution
confocal microimaging device based on a column polarization vortex beam. The super-resolution
confocal microimaging device comprises a pinhole filter, a collimating lens, a polarization and phase transformation
system, a
pupil filter, an
optical filter, a
detector and a three-dimensional translational platform, wherein a beam emitted from a
laser passes the pinhole filter to obtain a Gauss
basic mode beam, the collimating lens collimates the Gauss
basic mode beam into the
parallel beam, the polarization and phase transformation
system allows the
parallel beam to pass and obtain the column polarization vortex beam with preset polarization and phase distribution, the
pupil filter allows the column polarization vortex beam to pass and to be reflected through a
beam splitter and focused on a to-be-detected sample through a collecting lens, light signals reflected from the sample pass the collecting lens and the
beam splitter to be incident on the
optical filter, and the
optical filter only allows a
fluorescence signal of the light signals to be transmitted, the
fluorescence signal is focused on a detecting pinhole through the collecting lens and is detected and converted, through the
detector, into an electrical
signal to be output, the sample is placed on the three-dimensional translational platform, detection of the sample at different positions can be realized by moving the three-dimensional translational platform, and accordingly three-dimensional scanning imaging of the sample can be realized.
