A typical sketch of the experimental scattering geometry with a half-wave plate.
The orthogonal coordinates (a–c) represent the experimental coordinates, where the incident light propagating along ā had a polarization direction along c axis. When the polarization direction of incident light is inclined θ/2 with respect to the optical axis of the waveplate, the polarization plane of incident is rotated by θ while that of the scattered light rotates by −θ.
