Abstract:
Simultaneous recording of two data pages by dual-channel polarization holography is experimentally demonstrated. Two data pages are transferred as two orthogonal scalar wave components of a vector wave. The signal vector wave and reference beam are superposed on a polarization-sensitive medium. The two recorded data pages are simultaneously and independently reconstructed. Furthermore, holographic angular multiplex recording is performed.

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...
