Arxiv
|October 4, 2023
Summary
Phase diversity aberration correction in microscopy performs best with Poisson noise models, outperforming Gaussian models in most simulations. The Poisson model offers greater robustness for widefield imaging systems.
Area of Science:
- Optical imaging
- Microscopy
- Image processing
Background:
- Phase diversity is a computational imaging technique for correcting optical aberrations.
- Aberration correction is crucial for high-resolution imaging in microscopy.
- Existing phase diversity algorithms primarily use Gaussian noise models.
Conclusions:
- Poisson noise modeling is recommended for phase diversity in widefield microscopy, offering improved performance and robustness.
- The choice of noise model impacts aberration correction efficacy and computational efficiency.
- Both deconvolution and re-acquisition are viable strategies, with their relative merits depending on specific imaging scenarios.

Phase-Contrast Microscopes
In-phase-contrast microscopes, interference between light directly passing through a cell and light refracted by cellular components is used to create high-contrast, high-resolution images without staining. It is the oldest and simplest type of microscope that creates an image by altering the wavelengths of light rays passing through the specimen. Altered wavelength paths are created using an annular stop in the condenser. The annular stop produces a hollow cone of...

Optical microscopy uses optic principles to provide detailed images of samples. Antonie van Leeuwenhoek designed the first compound optical microscope in the 17th century to visualize blood cells, bacteria, and yeast cells. In 1830, Joseph Jackson Lister created an essentially modern light microscope. The 20th century saw the development of microscopes with enhanced magnification and resolution.
