From: Three-dimensional chemical mapping using non-destructive SEM and photogrammetry
SEM/EDXS photogrammetry. (a) EDX spectrum of the WC-Co insert tool. (b) EDX map of the top surface of the insert tool overlaid on the BSE image, obtained through averaging 8 maps acquired with a dwell time of 200 µs (total time for each map ≈ 5.46 minutes). Different colors correspond to different chemical elements, W (orange), Al (light blue), C (violet). (c) Steps followed for performing the fusion of a 3D mesh reconstructed using BSE images with the texture reconstructed from a series of EDXS maps. (d) Nine representative EDXS maps from different viewpoints of a collection of 36 obtained by averaging 2 frames of 256 × 200 pixels acquired with a dwell time of 1 s (total time for each map ≈ 1.7 minutes). The series of EDXS maps was used to obtain the 3D models shown in Fig. 5.
