Figure 2: Computed fft spectrum for mse operating with both pems at their customary retardance (R 1 = R 2 = π) for perfect mirrors having no shift, δ = 0 o and equal reflectivity for S- and P- polarization. A field-line pitch angle of 24 o with respect to the pem optics is assumed. Magenta vertical lines indicate the frequencies corresponding to simple harmonics of the pem frequencies. The blue lines represent the fft amplitudes that are close to frequencies expected for ideal mirrors listed in Table 1. In subsequent plots, green lines represent fft amplitudes that are near frequencies expected from the non-ideal mirror characteristics. 4
Figure 3: fft spectrum for mse operating with both pems at their customary retardance (R 1 = R 2 = π) for perfect mirrors having no shift, δ = 0 o and equal reflectivity for S- and P- polarization. A field-line pitch angle of 24 o with respect to the pem optics is assumed. This is the same case as the previous plot, Fig. 2, but plotted on a log scale to allow the identification of low-amplitude components. 5
