Figure

Fig. 2 presents two photographic views of the camera arrangement in the out of plane translation experiments em ployed to simultaneously acquire (a) stereovision images using the two outer cameras and (b) single camera images using the center mounted camer
Fig. 6 shows typical horizontal (U) and vertical (V) displace ment fields obtained using (a) a 2D system with standard lens, (b) a 2D system with telecentric lens, and (c) a stereovision system with standard lenses
Fig. 12 shows (a) the typical horizontal (U) and vertical (V) displacement fields obtained using a 2D system with standard lens and (b) 3D displacement fields using a stereovision system with standard lenses for an out of plane rotation experimentFig
Fig. 15 presents typical 3D DIC measured e xx and e yy values along a vertical line (x s0 ¼ 660 pixels) as a function of distance from the rotation axis for yE151; similar results are obtained for all rotation angles.
