Abstract:
We discuss the general properties of optical imaging in three-dimensional object domains from an information-theoretic standpoint, expressing system performance in terms of imaging mutual information (IMI). We use IMI to characterize volume holographic imaging, a new optical imaging method with depth discrimination capability. The performance of this holographic method in imaging a simple discrete, axial fluorescent object is compared with that of two alternatives: a pinhole-based system and a combined system that uses both a pinhole and a hologram in parallel.

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...
