Figure 25: Calculated time dependence of intensity of light passing through the mse diagnostic optics including pems assuming that only pem-2 is operating. A pitch-angle of 24 o is assumed, and perfect optics are assumed (δ = 0, R m = 1.0). The time dependence is illustrated for various assumptions of the maximum retardation imposed by pem-1 from π to 2π radians. The nominal retardation value is π. 30
Figure 26: Calculated ratio of fft amplitude at 4ω 1 to the amplitude at 2ω 1 as a function of retardance of the pem-1 for a situation where the mse diagnostic is operated with only pem-1 active. The calculated ratio is independent of the phase shift imposed by the mirrors, δ, and also independent of the pitch-angle of the field line. 31
