Phase-gradient reconstruction from photon-limited stellar speckle images
Abstract:
The phase-gradient process for reconstructing stellar speckle images is implemented in a photon-address mode for application to images containing small numbers of photons. Comparisons are made with an address-mode Knox-Thompson process which show that the phase-gradient approach has computational advantages and better SNR performance. Reconstructions from simulated data and real data for the binary source Beta Delphinius are presented.

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...
