2D and 3D Brillouin images of the PMMA lens.
(a) Schematic of the cross-section that was scanned by the beam line. (b) Cross-sectional Brillouin image of the PMMA lens at the location indicated by the dotted line in Fig. 4a. The colorbar represents the Brillouin frequency shift with a unit of GHz. (c) Schematic of the 3D scanning of the PMMA lens. 3D images were obtained by scanning the cross-section in z-axis. (d) 3D Brillouin imaging of the PMMA lens. Each slice represents a cross-section image of the PMMA lens at a location along z-axis.
