Deconvolution filters for resolution improvement in synthetic aperture digital holographic microscopy using speckle
None:
Digital holographic microscopy (DHM) using speckle illumination is one of the methods for spatial resolution enhancement and image quality improvement of reconstructed images. In resolution enhancement in using this method, the contrast of reconstructed images decreases because the amplitude transfer function in an optical system is modulated with speckle illumination. In this study, we report a theoretical derivation of deconvolution filters for improving image contrast in synthetic aperture DHM using speckle illumination and the application of the filters to experimental data.

Phase Contrast and Differential Interference Contrast Microscopy
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...
