OPTICAL REVERSIBILITY THEOREMS FOR POLARIZATION - APPLICATION TO REMOTE-CONTROL OF POLARIZATION

Using Jones's formalism, we prove three optical reversibility theorems that relate the polarization ellipticity at the output of an optical system to the polarization of the retroreflected light at the input. W e describe how these theorems can be used to measure the ellipticity o f a polarization remotely and thus to control it remotely. As an examp le, we use this method to create a linear or a circular polarization a fter a total internal reflection inside a prism, and the impurity of p olarization is found to be better than 10(-3). Finally we describe the use of this remote control to create polarization configurations that are useful for laser cooling of atoms.
