Abstract

To improve the resolution of the CW STED microscope using azimuthally modulated excitation beam modulation, phase retardation and various aperture conditions are simulated and tested. The ring-shaped aperture improves lateral resolution while suppressing axial direction elongation, making it suitable for 3D superresolution imaging of STED microscopy.
