Experimental setup for the high-speed 3D imaging system used for vibrometry. (a) Schematic of the experimental setup. (b) Photograph of the experimental setup. In the figure, M represents mirrors, HWP represents half-wave plates, PBS represents polarization-beam splitters, L1 is the 150-mm focal length convex lens, L2 is the 50-mm focal length convex lens, QWP represents the quarter-wave plates and BE is the beam expander.
