Figure 5
Three target surface shapes are fitted using the methods described herein. (a) Fitting is applied with 17 actuators plus constant and linear terms, and uniform weighting across the domain. (b) The constant term is removed and the linear term is replaced with tilt for beam stabilization downstream. (c) The mirror actuation of (b) is applied with Gaussian amplitude weighting. The vertical tick marks on the x axis indicate the mirror's central point of intersection; in (c), the intensity FWHM limits are shown. Below each shape, the longitudinal positions and widths of the 17 actuators are shown, staggered for clarity. The fitting r.m.s. differences are shown below each fit.
