A method is described for the calibration of a nonexact quarter-wave plate. This method makes use of the sensitive dependence on the retardation angle, for retardation angles near 90°, of the functional relation between the orientation of the quarter-wave plate optical axis and the orientation of the polarization ellipse major axis, both with respect to the axis of the initial linear polarizer.
