12 We have assembled and used several different phase-modulated optical polarimeters to measure transient retardance and molecular orientation angle in complex fluids and materials. The main difference in the instrumentation of the polarimeters lies in their modulation technique. Three different phase modulation techniques were used. These included techniques incorporating photoelastic, electro- optic and liquid crystal elements as the modulation source. The precise measurement of a material's retardance and average molecular orientation angle depends on an accurate calibration within the modulation range. In this paper, we address some of the problems associated with phase-modulated polarimeter calibration and techniques used to overcome them.
