(a) PSD function of the distorted mirror surface. (b) Two surface height errors with same PSD function. (c, d) Ratio of sinusoidal and cosinusoidal terms in their Fourier decomposition for the corresponding two errors. (e, f) Intensity profiles distorted due to the two types of errors. (e) Intensity after a mirror with a height error consisting of mainly cosinusoidal terms in the low frequency range. (f) Intensity after a mirror with a height error consisting of mainly sinusoidal terms in the low frequency range.
