• Polarimetry — is the measurement and interpretation of the polarization of transverse waves, most notably electromagnetic waves, such as radio waves and light. Typically polarimetry is done on electromagnetic waves that have traveled through or reflected,… …   Wikipedia

• Methods of detecting extrasolar planets — Any planet is an extremely faint light source compared to its parent star. In addition to the intrinsic difficulty of detecting such a faint light source, the light from the parent star causes a glare that washes it out. For those reasons, only a …   Wikipedia

• Optical rotation — (optical activity) is the turning of the plane of linearly polarized light about the direction of motion as the light travels through certain materials. It occurs in solutions of chiral molecules such as sucrose (sugar), solids with rotated… …   Wikipedia
