A mathematical description of photoelastic polarization modulators is developed for the general case in which the modulator exhibits a static retardation that is not colinear with the dynamic retardation of the modulator. Simplifying approximations are introduced which are appropriate to practical use of the modulators in polarization measurements. Measurement errors due to the modulator static retardation along with procedures for their elimination are described for reflection ellipsometers, linear dichrometers, and polarimeters.
