Abstract:
We propose an optical configuration to achieve symmetric and high contrast ratio (CR) in three-dimensional (3D) polarization switching (PS) displays. This optical configuration is accomplished using three retardation films and a λ/2 retardation switching panel. Typically, λ/2 retardation switching in the PS panels has an unanticipated asymmetric CR on the left- and right-hand side of 3D glasses because of the wavelength-dependent phase dispersion. To overcome this problem, we designed an optical configuration and applied it to the electrically controlled birefringence (ECB) cell. As a result, symmetric and high CRs are obtained for the 3D PS display.

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...

Stereoisomerism
Isomers are different chemical species that have the same chemical formula.
Transition metal complexes often exist as geometric isomers, in which the same atoms are connected through the same types of bonds but with differences in their orientation in space. Coordination complexes with two different ligands in the cis and trans positions from a ligand of interest form isomers. For example, the octahedral [Co(NH3)4Cl2]+ ion has two isomers (Figure 1) In the cis...
