With a combination of wave plates in the order [tex]\lambda[/tex]/2 - [tex]\lambda[/tex]/4 - [tex]\lambda[/tex]/2 it should be possible to achieve any polarisation. But I don't understand why: the first wave plate switches the polarisation direction, the second changes linear to circular polarisation and vice versa, and the last one switches it back again. How does this align the polarisation?
