This is a method to generate and detect any state of polarization using two liquid crystal (LC) retarders with retardances
and
and a polarizer. The two LC retarders have their fast axes at azimuths of
and
with respect to an external reference direction. The complex variable
is calculated using the Jones calculus. The equation for
indicates that different states can be obtained by controlling the retardances.
