Abstract:
Quantitative assessment of critical dimensions of sub-wavelength structures, dark-field and bright-field modes of operation, recognition of nonpatterned anisotropic surfaces, and three-dimensional profiling of opaque and transparent samples are the new features of a super-resolution dual-channel heterodyne microscope that was introduced in a previous publication in this journal. The aforementioned modes of operation can be activated by simple rotation of a polarizer or insertion of a polarization-separating prism. Various experimental results are presented, demonstrating new performance capabilities of the heterodyne microscope.

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...
