Principal investigator : Miguel A. Alonso
Keywords : polarization, SEO, q-plate, shearing interferometry, birefringence, scatterometry.
This work involves the measurement of nanostructures by using light with tailored polarization distributions, the measurement of the phase of light by using polarization-modifying optical elements, and the measurement of the polarization of light. These measurements are based on the use of spatially-varying birefringent optical elements such as stressed-engineered optics (SEOs) and liquid crystal devices.
