Depth resolved imaging by digital holography with an illumination of constantly changing curvature
Abstract:
In this Letter, a single wavelength digital holographic method is proposed to achieve depth resolved imaging by recording a series of holograms in the reflection geometry with an illumination of constantly changing curvature. A proper algorithm is employed to selectively generate the images of the object at different depths, including the phase and the modulus information. Theoretical analysis is supported by a visible light experiment to illustrate the feasibility of the proposed method.

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...
