FIG. 5.14 (a) Multi-frame averaged STEM image of silicon measured with [110] zone axis and histogram of inter-atomic distance along the (b) x and (c) y direction ( Yankovich et al., 2014 ). The scale bar in (a) is 400 pm. The error bars in (b) and (c) are the square root of the frequency, the curves are the best-fit normal distributions, and σ represents the standard deviations. Reproduced with permission from Yankovich et al., Nat. Commun. 5 , 4155 (2014). Copyright 2014 Springer Nature.

..., one reality that may go unnoticed is that actual focusing spots on targets frequently differ from the designed values due to heliostat surface geometry deviations caused during the manufacturing, assembling, and field installation processes. As a result, the effectiveness of an optimized aiming...
