Spinning pupil aberration measurement for anisoplanatic deconvolution

Area of Science:

• Optical microscopy
• Image processing
• Wavefront sensing

Background:

• Microscope aberrations are typically corrected within a small area (isoplanatic patch).
• High-resolution imaging of large specimens requires full-field aberration correction.

Purpose of the Study:

• To develop a novel wavefront detector for measuring aberrations across the entire field of view.
• To enable anisoplanatic reconstruction for high-resolution wide-field imaging.

Main Methods:

• A novel wavefront detector using pupil sampling with subapertures was developed.
• Aberrated wavefront phase was measured at each specimen position.
• Region-wise deconvolution was applied for image reconstruction.

Main Results:

• The developed detector successfully measured wavefront aberrations across the entire field of view.
• Anisoplanatic reconstruction of the sample image was achieved.
• Full-field aberration measurement and correction were demonstrated in a wide-field fluorescence microscope.

Conclusions:

• The novel wavefront detector enables full-field aberration correction in optical microscopy.
• This technology facilitates high-resolution imaging of large specimens.
• The method is applicable to wide-field fluorescence microscopy.
