Curvature fields (a) ∂2W/∂x2, (b) ∂2W/∂y2, (c) ∂2W/∂x∂y and (d) ∂2W/∂y∂x. (e) First (single) raw image of the 2D mesh scan of the speckle generator. The beam passes through the speckle generator and is reflected on the mirror before impinging on the detector. (f) 3D rendering of the mirror's tangential slope error. The darker surface shows the slope error obtained with the ESRF Long Trace Profilometer.
