Abstract
Hyper Rayleigh scattering is frequently used to determine the 6 rotational invariants of the first hyperpolarizability tensor. It requires numerous polarization-states of both incident- and scattered-light and thus justifies the use of a dual-rotating-retarder polarimeter. Optimization of our experimental setup by reducing the condition number of the polarization processing matrix allowed us to get optimal detector angle and retarder angular steps for two experimental configurations. Next, we calibrated our experimental setup by using a quartz plate sample in a two steps procedure: at first the first retarder then second one. The retardance and ellipticity angle of both retarders were estimated by minimizing a chi-square function. We estimated the standard deviation of each parameter from noise spreading and performed this calibration procedure for two experimental case-studies, i.e. two angular positions of the quartz sample.
