Abstract

Recent studies on the behavior of nematic liquid crystals (LC’s) in two basic configurations are described. The phase rate of change Δϕt is studied for the case of parallel aligned nematic cells. It is shown that Δϕt of approximately 3 rad/msec can be obtained with a 4-μm E-7 LC at λ = 0.63 μm. The optical transmission of a 900 twisted-nematic cell is studied with regard to its dependence on the polarization angle of incidence.
