Description

technical field [0001] The invention relates to the technical field of super-resolution imaging, in particular to a single-channel optical super-resolution imaging instrument. Background technique [0002] Today's nanotechnology is increasingly becoming the frontier of natural science and technology development, such as the construction of new electronics and new photonics at the nanometer level, the synthesis of new surface catalysts at the nanometer level, and the wide use of new nanoparticles for biological (fluorescence) labeling Wait. The development of nanotechnology is inseparable from nanomicroscopic imaging technology, which has become the standard configuration of many laboratories represented by scanning electron microscope and atomic force microscope. However, optical detection technology has a strong advantage in studying microscopic internal states such as electronic structures, phonon states, and plasmons at the nanoscale. However, limited by the optical diff...
