Fig. 12.


Adaptive optics bench performance results for various misalignment scenarios. Solid and dashed lines, shaded areas: same as in Fig. 11; top row: H-band S.R. computed from the phase residuals; bottom row: measured S.R. in the R band, relative to bench focal camera nominal alignment (≈80% absolute S.R.). Results are shown for rMod = 6 λ/D, which is close to minimal operational radius on bench due to PWFS prism edge roughnesses of approximately 30 μm (1 λ/D) width. Cross markers: measured R-band S.R. is undetermined (explanations in the text).
