Tsang's resolution enhancement method for imaging with focused illumination

Area of Science:

• Optical Microscopy
• Super-resolution Imaging
• Photonics

Background:

• Overcoming the diffraction limit is crucial for advanced microscopy.
• Structured illumination microscopy uses patterned light for enhanced resolution.
• Spatial mode demultiplexing offers sub-diffraction resolution at the detection stage.

Purpose of the Study:

• To investigate the synergistic effects of combining spatial demultiplexing with image scanning microscopy.
• To experimentally validate the enhanced resolution and image quality of this combined approach.

Main Methods:
