Retrieving true images through fine grid steps for enhancing the resolution beyond the classical limits: theory and...

Area of Science:

• Microscopy
• Image Processing
• Nanotechnology

Background:

• Direct imaging systems face limitations in resolution improvement.
• Achieving finer grid steps than optical or acquisition limits is challenging.

Purpose of the Study:

• To develop and test a novel method for retrieving true images with a resolution finer than microscope limits.
• To overcome limitations in direct imaging resolution improvement.

Main Methods:

• Utilizing random 3D relative displacements of objects.
• Employing a reference object fixed to signal objects to avoid displacement measurements.
• Rearranging low-resolution images acquired at matrix pixel size to create high-resolution images.

Main Results:

• Demonstrated good quality of retrieved images.
• Successfully visualized and detected small, convolved objects not visible in captured images.
• Showcased the potential for resolution below 10 nm with deconvolution procedures.

Conclusions:

• The novel method offers promising opportunities for super-resolution imaging.
• It enables effective application of inverse algorithms for resolution enhancement.
• Potential for achieving nanoscale resolution below 10 nm is demonstrated.
