Description

By applying a voltage to a liquid crystal variable retarder, it can produce different polarization states of light, by introducing a phase shift, or a retardance. It is necessary to understand the behavior of the LCVR as the applied voltage varies across it. First, a retardance curve is experimentally calculated for two different wavelengths, and then the deflection of light is measured at different retardances. It was found that the retardances produced by the variable retarder is wavelength dependent, and there appears to be no measurable deflection in the direction of the light at different retardances.
