Abstract:
In this paper we study both theoretically and experimentally a method to characterize the amplitude and phase of a paraxial optical beam. The method is based on the spiral phase interferometry technique, recently proposed. We theoretically analyze how to adapt the original proposal to deal with the special characteristics of finite optical beams. Finally, we compare a series of numerical and experimental results to show the advantages and limitations of our proposal.

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...
